Beautifully simple

Love this knife. The opening is very fast and smooth. The knife has what I think is an elegant look in its simplicity. The pocket clip is tight and the blade is sharp. I use it for everyday carry and light cutting. The tip is pretty thin though, definitely not good for prying.

High Quality Knife

I bought it as a gift for my daughter. It was very high quality. The assisted open works very well and we loved the sleek design. I plan on getting one for myself.

Best Every Day Carry

I have five of these, two with the two steel blade, two with s30v, and one with zdp 189. I bought this one to give as a gift to my son in law after he seemed impressed with the one I was carrying. I've always liked drop point knives and this one fits my hand perfectly. I mainly use it for opening packages and cutting fruit. The Leek is thin and fits well in the pocket. The safety lock sometimes locks all by itself, but it is definitely a one hand knife which came in handy when I was acosted outside a McDonalds one night.

Kershaw 1660 Leek

This little knife is almost indesctructible . A few years ago I was fortunate enough to have been gifted a Kershaw Leek by my Uncle Mike Los Banos . I carried it almost for a year as a secondary back up knife . One day I had loaned my primary EDC to a coworker , left alone with my Leek I proceeded to cut open some heavy boxes . Thinking that it was an "el cheapo" knife I went to town cutting boxes popping staples out of heavy cartons . The Leek exceeded all of my expectations ! It never got dull to the point of tearing cardboard ! Just a few short strokes on a Spyderco Sharpmaker it popped back with a screaming sharp edge . I even used it as an icepick a few times without any breakage . The blade locking mechanism took a while to get used to , it's great not having a knife not opening in your pocket . I had recently picked up a lot of these at a fantastic price and gifted a few family and close close friends with them . All of them were instant favorites among the other EDC knives that people often carried . Uncle Mike was and is still very pleased that I had "paid it forward" with these awesome little blades .

Cool Knife

A really good knife but be careful with it though it is razor sharp. I really like the fast action on it. The only flaw it has is the locking mechanism is a little loose. Kinda afraid of it flipping open in my pocket. Overall it is a good knife! It's like cool and stuff ha ha ha ha.

I was sceptical at first as I'd not previously owned a stainless blade that could compare with good carbon steel, but this one does. I've had a small pocket knife in my pocket since I was a small boy and so far this is the best of them. I bought one on a whim, used it everyday for a few years and then lost it, as I occasionally do. This time I've bought three just in case. I like to take the clip off as for me it's unnecessary. I use mine for everything from opening christmas presents to eviscerating game and it does a fine job.

Wht it's even better than its glowing reviews.

I've owned one for years and love it. It's a dedicated slicer par excellence. Take highend Swedish razor steel, enhance its knife blade qualities with Kershaw's collaboration (same folks as Zero Tolerance, BTW, for you name droppers) and create a hollow ground slicing blade in a very compact package. I carried mine (after removing the pocket clip) in my regular size wallet as a backup to my main EDC pocket knife. I only replaced it as my ready backup (still in my wallet) when the flat ground Kershaw Link became available in 20CV (a more general purpose heavier use grind, though not quite as sharp as the Leek). I also removed the irritating "safety" that was only designed in because at the time the Speed Safe mechanism was new to the market and had'nt proven its inherent safety yet. This is a great classic pocket knife, no matter how many other knives you own. Oh, and it comes with a life time guarantee and free sharpening from Kershaw. So any problems over time can be solved easily

Every day carry, best I've owned.

I'm a 40yo owner/operator of a small farm, and a full time college student. I've been carrying one of these knives for about years now. It's the best every day carry knife I've ever owned. It's blade geometry means it cuts cleanly and quickly, but still has a lot of strength. I know I shouldn't pry things with it, but sometimes its the only tool at hand. It keeps a good edge for a long time, and as long as you don't let it get too dull, it's not really hard to hone. It's slender, and doesn't fill up my pocket. The one-handed operation is great. If I lost this knife today, I'd be replacing it as soon as I determined it couldn't be found.

Stop calling it "razor sharp"!

Yes, this is a FANTASTIC knife for the price, and I agree with everyone who has reviewed it and labeled it the “best EDC knife” because that’s exactly what it is. The one thing it is NOT however, is razor sharp. That’s my ultimate pet peeve with all these knife reviews is people who use the term “razor sharp” to describe the way these EDC folding knives come from the factory. Anyone who uses that term needs to go to their local drugstore, buy a pack of razor blades for $5, and then compare an actual RAZOR BLADE to their new knife right out of the box and it will be extremely obvious how woefully inaccurate the term “razor sharp” is when applied to these blades as they come from the factory. Can you make them razor sharp? Sure. The 14C28N steel in these Leeks is the successor to the 13C26 that was designed for scalpels, so yes, you can make them razor sharp, but then if you use it for everyday tasks the edge simply won’t last very long and you’ll end up spending a lot more time sharpening you knife than actually using it. Anyhow, rant aside, I love the leek, and I love the design of it. It’s a lot lighter and sleeker and easier to carry in my pocket than my Blur or my Manix 2 since both of those have much rougher grip surfaces which make them a little more difficult to remove from the pocket. I know some people don't like the bead blasted steel, but my hands don't sweat much so it works fine for me. Plus, if you do want a razor sharp knife this is a good one to start with due to the nice straight cutting edge, just be ready to do some work to get it there.

I own four of these knives - two in my bugout bags and two for daily use. I like them small to fit in my pocket with no discomfort. Easy and quick to sharpen. Make a great compliment to my small Sig. Plan to give an Onion to my grandchildren when each reaches the appropriate age. Go with the serrated blade, it's worth the extra cost.

Perfect pocket EDC

I just bought this and it’s the perfect EDC pocket knife. The size is just right and the quality is excellent. I also think the price is very fair for a USA made knife. When you can get this quality for this price why bother with a cheaper import? I did flip the pocket clip as I prefer a tip up carry, and while the action is a little stiff - it will open up soon enough with use - the SpeedSafe action is addictive. The Sandvik 14C28N blade steel isn’t quite top level but is still more than adequate. I’m very glad that I have this.

Kershaw Leek is a Perfect EDC

This knife replaces a CRKT pocket knife I recently lost. Fit and finish on the Leek is amazing and the blade comes razor-sharp. The assisted opening makes one-handed deployment a breeze and is plenty fast. Although the handle is not textured, grip has been more than adequate for the light to moderate duty my knife is subjected to. I recommend this knife, without reservation.

Fantastic knife!

I bought this knife to replace a black version that I lost(Found it a month later!), and it also has performed beyond my expectations! Phenomenal quality, sharp right from the box,lightweight,opens easily w/thumb or flipper, and it sharpens easily, and a safety that works(I never use mine and never had a mishap!). The only thing I don't like is that the clip is set up for right hand only. I removed the clip, and I carry this one when I go to states that freak out when they see a pocket clip. Great knife!

I just bought 2 more non-serated Ken Onion Leek knives as gifts after enjoying mine for several years. In my opionion, it's the best value in a folding knife. Cool features: VERY sharp, right out of the box. Flips out easier than most knives, no plastic. Fine point, perfect for removing splinters, opening envelopes, etc. Try it. You'll like it!

I like how it feels in my hand. It has a sleek design, along with a rapid opening sharp blade. I am new to pocket knife collecting; but my first impressions were good.. I will use it as a pocket knife for simple handy cutting and some boxe cutting for the recycling bin.

Heavy Duty EDC for 6 Years

Carried this knife daily for the past 6 years and have used it for rigging, fish and game cleaning, cabling, camping, open ocean sailing, kayaking, canoe paddling, scuba diving an all manner of abuses it was never designed for. The safety broke in mid 2005 but it's never sprung open unless dropped on hard surfaces. The brushed finish on the blade and handle are a bit scratched up, but periodic strip down, cleaning, lube and sharpening keep the action smooth and the edge as sharp as the day it was bought. Pack the spring steel torsion bar with some 'Muscle Grease' from Penn Reels, spray silicon lube on the rotating parts and it works fine under water.

Fantastic Knife

I am on my 3rd Leek - not because of knife failure, but moreover my propensity to misplace/lose stuff. Having said that, I do wish the tension of the pocket clip maintained the same integrity as the edge sharpness. Also, the contour of the cutting edge makes sharpening (if eventually required) very simplistic and efficient. I totally fail to understand the one report which characterized the quality of the blade as poor; I suggest that, although the reviewer claimed her husband didn't mistreat the knife, I think he was attempting to use it as a prybar, and not a fine-edged blade, and was embarrassed to admit the misuse of his wife's very astutely-selected gift.

Back to the edge of perfection

I'm in qualms over how to describe my affinity for this knife. Let's go back to 2004. I've had some cheap 'gas station' knives (I'm 41) up until then and I never really knew the difference until the Kershaw Leek MADE THE DIFFERENCE. My first "real" blade. As a bartender, a reliable knife soon becomes paramount. From processing inventory (boxes) to defending oneself from drunken evildoers, the Kershaw Leek had been there for me time and time again. Also, in the 5 years that I owned said Leek (it was stolen from me and now 16 yrs later I am buying my 2nd one), I only had to sharpen it once. So smooth in its opening, in its handling, and in its sexy lines. If you are on the fence about adding this knife to your cart, once you have the Kershaw Leek in hand, you'll understand why this has permeated throughout the knife world as one of the best damn EDC knives to ever grace a palm. Peace and safe living...

Love everything but the pocket clip!

I have the Leek with the speedsafe and the liner lock. The lock up is great, sturdy and have no doubts that it'll accidentally close on my fingers. The tip lock is decent. Especially since it doesn't take much pressure at all on the flipper to make it spring open. The ergonomics are actually amazing, one of the best imo which you wouldn't think it would be anything special by just taking a look at it. But very comfortable! Only thing I reeeally dislike about it is the pocket clip. I love.my knives to be tip up carry but with the clip like that there's about a full inch of knife sticking up out of your pocket! And the clip is about 3/4 the length of the handle itself! Although when gripping the knife the clip does form great in your hand, I'll give it that. Just had to voice this opinion because I couldn't seem to find one since other person to mention anything about the pocket clip. Still give it a 5/5 tho. Great job Kershaw?

The Kershaw Leek Is One Of The Best Budget EDC Knives You Can Buy!

The Kershaw Leek has an excellent iconic Ken Onion design that makes it unique, unlike many other knives. I fell in love with the design from the beginning of my EDC journey and the Leek was the first knife of my now ever-growing knife collection. The speed-safe is very easy to get used to and it is nice to have an assisted knife in a sea of non-assisted folders. The security mechanism is very annoying and I ended up taking it off all together because it will constantly locks the blade every time I needed to open the knife. I like that at least the have the option to keep it on or take it off to your liking. The ergonomics are great and it's built very strong to last a long time. It has also retained a great edge even after 6 months of nonstop use. I go into more detail on my youtube review if you are interested and want to check it out: https://youtu.be/YNzr78npSWk

It's legal. It's simple to use. Just taking it out of my pocket, (opened), scared off a nutcase road rage driver. Don't leave how without it. Oh and it's a solid knife. I checked a 'top quality' sports store and their knives were shoddy by comparison.

I bought this knife about a year ago and carry it most every day. It holds an edge really well and fits nice and flat in my pocket. Easy quick opening is nice too. The little safety stop broke at one point and I got a few "surprise" openings of the knife but I can deal with that. Unfortunately somebody stole this knife from me and I promptly replaced it with the exact same thing, hence my purchase today.

Great Knife

This knife has about the tightest lockup of any of my knives. I can't perceive ANY play in the mechanism as of yet. This may change over time, but I've got brand new Benchmades at twice the price that have more wiggle room. On top of that the spring assist makes this the fastest deploying knife I've got. The blade is razor sharp and holds its edge very well. I haven't needed to sharpen it since I got it. All in all I'd say this baby is made of win.

The shipping was super fast and tracked the whole way. Once I received this knife I knee what I was getting but was even more satisfied then expected. This is razor sharp with an amazing tip. After a lot of use still a great edge and that needle point is still there and strong. Great quick release and the lock is nice if you want that extra comfort. Would definitely buy another one.

Opens lightening fast one handed, holds an edge well and sharpens easily. Am going to order another just to have on hand. I have a Benchmark nearly the same size, but a little bulky to suit me as an everyday pocket tool and this knife is every bit as much as the Benchmark at way les the price.

Excellent Knife

I came by this knife as part of my search for a new EDC after having lost my S.O.G. Flash II which I carried for many years. Wanting to upgrade without spending alot more money I began reading and researching, and three knives came up as the "best: the benchmade mini grip, the kershaw leek, and the spyderco delica 4. Of the three I bought the BM and leek, but substituted a spyderco tenacious for the delica (big mistake). Differentiating the leek and the mini-grip is somewhat hard. Both came razor sharp out of the box, both are perfectly sized for EDC (thin, sit low in the pocket), and both have similarly sized blades. The only real difference between the two is the locking mechanism. On the mini-grip you have the axis lock system which prevents the blade from opening EASILY when the lock is engaged; when disengaged the blade swings open freely and is excellently balanced for one-handed opening. On the Kershaw the locking system is either on or off, and when on the blade cannot open and when off the blade opens with the assistance of a spring. As a matter of personal preference I prefer the mini-grip because I don't need to worry about hurting myself if I forget to engage a safety before pocketing the knife. In addition, being a law student living in CA (where a criminal offense would prevent my admission to the Bar), I am hesitant to carry an assisted opening knife with a blade shaped like the Kershaw as the statutory definition of a stabbing weapon leaves police a good amount of discretion in finding a pocketknife to be illegal. The mini-grip's lack of an assisted opening mechanism (which doesn't impede rapid opening) along with its blade profile mean that I carry it with confidence that I am well within the bounds of the law.

My all-time favorite of any knife I have. I have the Kershaw shallot, the Kershaw amplitude 3.25, the Kershaw skyline, The Kershaw fatback , and Kershaw scallion. But I have zero complaints about any of them, each just as sharp as you would expect from Kershaw straight out of the box. It has a Great balance of weight to size ratio it really feels like a bigger knife then it is in your hand. It just feels exactly how you wanted to feel from a pocket knife and with the blastoff opening up the speed safe assist you can't go wrong for one handed operations!! This will be the knife I will always go to over any other and will be purchasing time and time again as the need arises. Truly recommend to anybody who is a fan of a pocket knife and appreciates good quality! Spot on Kershaw keep it going! Ken Onion is the best

Best EDC for both tux or jeans

This has been my EDC for more than 7 years. While it was razor sharp out of the box, it does tend to loose an edge quickly. It also sharpens easily. A little into my seventh year of carry the torsion bar broke. I emailed Kershaw who offered to repair the knife I'd send it to them or they would send me the parts to replace myself. I chose to repair myself which without even reading their instructions took maybe 30 minutes. That included completely cleaning everything in solvent and lubing. I've got a lot of other knives but none as comfortable to carry. The safety is slightly lame but I'm so used to it that it doesn't get in the way. Sliding it out of my jeans tends to take the safety off although I still go through the motion before deploying the blade. Coming out of a pair of dress pants I still have to slide the safety off. I bought a Leek for one of my Sons and had the handle engraved. The engraver did not have a laser, therefore he used his standard carbide tipped computer operated engraver. After about three passes he tried a diamond tip. While the engraving was visible, it had no depth. The guy apologized and didn't charge me. He said he'd never run across a knife handle that hard.

Kershaw Does Not Disappoint!

This US made Kershaw is a great pocket folder. The assisted flipper is fast and super useful as you can open it one handed. That's great when you're cutting rope or opening a bag of mulch or anything else. It look beautiful, is extremely sharp. The build quality is superior to most knifes I own, and I own some pretty nice knives. I'm a Kershaw fan for life.

The Leeks are really good EDC knives

I mostly use my knife for cutting stuff. I don't try to use it as a pry bar nor do I hammer nails with it nor cut through heavy brush. I bought the knife to cut stuff, even if I have my hands full. It does this quite well. I dislike the safety feature that prevents the blade from deploying as it is clunky and unreliable. The good thing about it is that you can adjust the tension required to deploy it. If you don't want to use it, you don't have to. Simply crank up the tension while in the unlocked state and it will stay there. I have never had this knife try to open up in my pocket while unlocked. While I don't use the factory configured tip-down pocket clip, I leave it on the knife for extra purchase on the handle. The blade style suits me for precision cutting and even breaking down the occasional box. I own much more expensive knives but, this is my favorite EDC knife and when I don't want to sharpen the blade anymore (which I rarely have to do), the replacement is cheap and convenient.

As others have said, this very high quality knife is quite sharp right out of the box, and the opening mechanism is simply awesome. And it's great looking, too, with excellent fit and finish. I do think I'll remove the clip, however, which will make it a great pocket knife -- light, sharp, and extremely easy to open.

It's plenty sharp out of the box, has a smooth opening and the pocket clip can be changed for your carry preference. I've always liked Kershaw and would definitely recommend them to anyone looking for a good quality, economical EDC. I also like the Wharncliffe-style bladed knives.

BEST Pocket Knife Ever and I have owned hundreds

The Leek is the best and most practical knife ever made. It fits in the pocket easily, opens at the touch, sharp, and most importantly it has a straight triangle edge that is easy to sharpen because there is no curve to the blade. Absolutely nothing negative about this knife. Its a little like keeping a razor in your pocket, but it even has a safety. I have bought hundreds of knives over the years because my dad had dealers license, but this is by far the best knife ever. Keep it in your pocket, use it everyday, get it dull, and no big deal to sharpen it back to razor sharpness in minutes.

A Near Perfect EDC Companion

This knife really hits it out of the park in just about every area. I will start with the blade. The shape of this blade is very different, but with the tip, and how thin it is, it really is very versatile. I find this knife able to cut and slice anything I ask of it. Did I mention the tip? It is perfect. The steel is also very good. It is not the hardest, but it holds it edge very, very well and takes a mirror edge surprisingly easy. Thumb studs may not be the best, but are usable and don't have to be used to open it, so take them or leave them; they aren't in the way. The flipper is very smooth and launches the speed safe opener perfectly. I will use either the studs or the flipper pretty much based on how I happen to be gripping it. The assisted opening is lightning fast, super smooth, and sends it to a perfect lockup every time. For the handle. It could be grippier, but it is not slippery in anyway. I have never wished for more grip on it. It is contoured well so your hand can really lock down on it. The lock is superb and doesn't allow any play, and I could never imagine its frame lock failing. The handle is also surprisingly scratch resistant. I really did not anticipate that. The lanyard hole is well placed and sized if you use it. The safety is like the thumb studs; take it or leave it. It works well, but is not necessary. Some people take it off, but I just simply tightened it down really tight. This way I can use it if I need it but it could never accidentally engage. I use it only when I do not clip it and drop it into my pocket for ever reason. With a tip up carry it is not necessary to use it as the seam of your pocket really holds it closed. I have never had it open in my pocket, not even slightly and do not see it ever happening. The blade detent is very good. My dad does use the saftey at all times on his. Like I said, Take it or leave it. One thing that surprised me was the blade centering. It does not rub and is not really that close to it, but it is just a frame lock thing so it does not bother me in the slightest. The fit and finish are superb. There is not one flaw or blemish on mine. When it is locked up it really feels strong, and none of the screws have tried backing out at all. Very well assembled and built. Now for the clip. The only reason for a 4 star rating is the clip. It holds well. It looks nice. It doesn't tear your pants, but is still snug. I don't like the positioning. It is too low, and the bottom of the knife is kinda pointy (rounded off) in shape and seems to poke out of the pocket just enough to ruin the perfect rating for me. I don't need a deep clip like the Flash 1, but it sticks out just enough with the wrong shape to not sit in the pocket as well as it should. Really is a shame and the reason that this is not my end all and be all of knives. Overall. Incredible knife that is built to last. Made in USA too which is always a plus for me. I have used the warranty service and they were great, with no hang ups. They even pay return shipping. The price is very good for what you are buying too. It could be a more expensive knife without my opinion changing. If you like a clip that does not sit too low, then this may be perfect for you. I love this knife and carry it very often, and if I can only find one flaw (more preference), then I think thats all about you could ask for.

Worth buying again!

I had an earlier version of the stainless leek and liked it so much I've since added other Leeks and other Ken Onion knives to my rotation. Sadly, I dropped my older stainless Leek a few months ago and it fell on a granite floor point first. Try as I might, I never could quite get the tip straight so when I saw this one at such a great price I had to snap it up! I gave this a 4 instead of 5 based on the "ok" but not great steel used.

A very nice and elegant folder

This is very nice and compliments my other small folders. Smooth, very sharp, very nice feel and flipper. The safety lock is very effective, but a bit clumsy one handed. Though this is not a defensive knife but a utility, other than last resort. Great value a very nice EDC. In fact my problem is that I have 3 particularly nice knife in this category, and try to carry them all on occasion ;-)

Nice but slippery!

My wife got me this one as a gift, it's my first Kershaw and although I'm more of a traditional folder guy, this is really, really slick. Maybe a little too slick, as the all-metal design gets really slippery even with a little sweat or water. You don't want to mess with this if your hands are wet, so maybe not a good choice for fishing or around water. The build quality on mine is superb, everything works with precision and the quick-flick opening is unreal, faster and more secure than a couple of autos I have. The metal has a silky feel, must be the final treatment they gave it but again, that makes it slippery to hold sometimes. Blade is sharp but it's very thin, so the edge seems like it will dull quickly, we'll see. The grind they put on it from the factory is pretty rough, all things considered, so needs some final honing work. It's also a bit heavy in the pocket at 86 grams. Overall though, very nicely made and what do you know -- they actually still make stuff in the U.S.A.!

Careful....

Very sharp out of the box. Very thin and easy to pocket carry. very easy to open. A good nimble blade for delicate work. The main draw back and positive at the same time is that it is so thin. You have to be VERY careful when closing it especially if doing so one handed as it almost becomes slippery to the feel and you can accidentally get a finger caught while closing. As noted, very sharp. DO NOT CLOSE ON YOUR FINGER!!

Overall its a great product for the price and its USA made. This was the knife that got me hooked on folders. Now I cannot get enough but I do go slightly higher in price/quality. Geared more towards Benchmade/Spyderco. But I must say KERSHAW HAS THE BEST WARRANTY compared to other competitors.

Thought it was stainless

I've had it for a day and there are already some small rust spots on the blade. Just thought that was a little premature for a "stainless steel" blade. I'm not in a wet enviroment either. Other than that, seems like a hell of a folder. Nice thin profile, robust pocket clip, very sharp edge and point, and "John Q Public friendly" blade shape. Some people complain that the tip is too thin, but its a knife, not a screwdriver. I also like that there is no texture on the grip to destroy my pants. I just wish that I knew Kershaw made a black version of this knife before I bought it (didn't check KC, got it from a local retailer). The brushed version looks good, but the clip and butt end stand out to much.

Very nice for the price.

I purchased this to carry in situations when I don't want to carry my more expensive PM2 knife. Build quality is very nice. I like the speed of deployment, it is very very quick. Lockup seems secure. Very light, I keep checking my pocket to see if it is there. I'm not to fond on the the blade profile as it is very pointed and if not careful you can easily stab your self. It also seems it will be break easily if any type of prying was to be attempted, but then again that is why I have many knives, In public it is much less intimidating than some of my other knives I carry. Also want to give Kershaw a big thanks as I managed to strip a screw changing the pocket clip location and they quickly sent me new ones free of charge. Nice! Overall very pleased with it and it secures a place in certain carry situations.

Heavy

I have had the small version of this knife for a couple of years and always liked the action so I purchased 3 of the larger version. I also like the action on this version though the knife is heavy for its size. A non slip surface vice the polished metal would be beneficial too. It feels like it wants to jump out of my hand sometimes. Maybe this type of action requires the metal scales, but I would like to see this action in a lighter frame/body. Having said that, I am a big fan of this knife and this company. The blade shape is excellent for small cutting jobs.

Good Knife

This is a great knife, very sharp and the assisted opening makes opening a snap. I wouldn't recommend it as a outdoor/camp knife due to the thin blade tip and all metal handle. The metal handle can get slick when your hands are wet or even damp causing the knife to be hard to grip. It makes a great pocket knife overall.

Kersaw Ken Onion Leak

Awesome knife, I've used it for field dressing, cooking, salt water fishing and multiple other needs. It's small enough to carry in a pocked (folded) yet long enough to be used as more than a box cutter. Blade keeps a sharp edge. Clip is a plus. Only down side, I use it so much I forgot where I put it last (field dressing). The only down side is that the tip is a little on the thin side and becomes easily bent if you are not careful with it.

Piece of art!

This knife is gorgeous. A bit small though for those with larger hands. This all stainless model is really something. Elegant and a pure design excercise. The only thing i would change would be to remove the Kershaw logo from the front scale and the pocket clip, and also make the markings on the blade much more umderstated. These markings detract from the simple and elegant lines of the knife. It came razor sharp and is very pleasing to handle. If i can find a plain stainless pocket clip for it i will replace the logoed one

Gorgeous looks, made for smaller hands

This baby is great, my real issue is that it's not big enough, and none of the pictures OF the knife had any sense of scale to them. It loses 1 star for being too small, and having a tip-lock-slider, which I missed when purchasing. Accordingly, I have gifted this knife to my wife and she is loving it.

I love this knife... BUT

As an EDC I love the knifes shape it's assisted opening and it's thinness. The problem is the clip doesn't hold it secure in my pocket, it needs to be much more robust. I lost one of these, replaced it. I will no longer use it as an EDC due to problem with losing things I like.

Light but flimsy

I purchased this knife a few weeks ago. It's very light weight and sharp. On the other hand though it will not stand up to really any abuse. It probably would work fine as a box cutter. The blade tip broke off on me with just moderate use, and after using it for something as simple as opening a few bottles, the assisted open started to fail. The locking mechanism also seemed a little stiff and wouldn't create what I would consider a nice positive lock. Overall I wouldn't recommend this knife even at the price. For another $20-$30 you can get a much much higher quality folder.

I like

I like the having the assist features on knives. It makes the opening a lot easier, but the way to lock isnt as easy as other knives. I also have knives of Gerber, Shrade, and Smith&Wesson that have the assist opening features and I hate to say, but I like that better. Now I love Kershaw steels. After I am able to get them sharpened to where I want them, then they are very easy to resharpen.

Nice Knife

I have had this knife for 16 months. I use it as a daily tool and it mostly sits in my pocket. The good: The knife is sleek, sharp, and like many others said, good for detail work due to how skinny it is. It is a robust knife and hopefully will last me a while The bad: It has started making a clicking noise when I use the spring assist to open it. The safety has broken off as well. I am not particularly rough with it so I am not sure why this has happened. Overall very happy with the knife.

Call the plumber! I Gotta Leek!

Or maybe I should call the Iron Chef. Old age is such a wonderful thing. This was the second Kershaw that I purchased, the first being a Cryo. I really like this. I scooped up several more on eBay. So why the three star rating? The handle is way too slick for my liking. I don't think I could patina it by leaving it in an onion. (Not Ken) But maybe if I left it in raw honey overnight, the traction would improve. I'm OK with the safety. The one-handed opening is great. My non-eBay one was perfectly centered. They are very easy to get sharp, DMT stones or SSM. It's also a bit on the thin side for my liking. Even tho I have some dislikes about this, I have no regrets about the purchase. I really do like the knife.

good but not exelent

Used this every day for last 3 months till i lost it in the field today, dont clip in you back pocket and expect it to stay. Very sharp out of the box, yes i had a very nice bald spot on the back of my hand for about a week. the blade tip seemed very fragile as i comes to a very slender point but never broke with my usage. My biggest dislike is the Safety Lock system, kinda makes it useless as a fast opener. once unlocked it would open with a flick of the finger but i didnt feel safe leaving it unlocked in my pocket. Also a chinsy black plastic piece between the sides on the "spine"? of the knife was kinda disappointing. i buy a beautiful all stainless knife only to have sh8tty black plastic visible. Yuck. getting something else this time.
