Very Good

The above knife looks and feels great. It is as described. However, I have not put it to any tests yet. If it holds up as well at it looks and feels than it will be truly great.

What are you waiting for?

It's the ultimate fighting knife! Just look at it! It screams bada**! Mine arrived razor sharp. Fit and finish are flawless. The sheathe is super high quality, with no looseness or play. The price can't be beat. I've seen this knife selling elsewhere for $99.99. Don't wait! Order yours today! I guarantee you will not be disappointed!

Trench Knife

This knife is strictly a last ditch fighting knife. When you're down to this being your last weapon, in a desperate situation ( been there, done that ) you cannot ask for a better one! I'm a black belt in Japanese karate, with some weapon training and this would be a devastating knife in a fight! Very sharp, for slashing to the right or left, a very strong tip for easy and deep penetration with little effort, through any clothing someone may be wearing including bullet resistant armor. The knuckles, built into the hand guard, will cause tremendous damage to head or torso, plus giving more support for a stabbing use. I'm retired military and law enforcement and I would like to have had a knife similar to this in a few remembered situations. For a defense weapon, I would pick this knife over any other I have seen. The weight and balance makes the use of it effortless and will not wear you out.

Great Knife

I have always been facinated with the "trench" knife but they are poorly made and expensive. Cold Steel comes to the rescue with the Chaos. I was concerned about the fit to my hand with the enclosed grip but it fits my hand perfectly. (x-large glove size) Even though it is made in Tiawan I am "assuming" it still meets the Cold Steel blade strength standard. Even so it is a lot of knife for the money. Very sharp edge.

Wow!

This is an amazing knife, especially at this price range. I'd been shopping for a fixed bowie/trench style knife for awhile and was attracted to those with a pronounced quillon. Then spotted this with the full handguard as well, and the punch pommel. It's a feature combo that I haven't seen on anything else. But I was not expecting the quality of both the knife and the sheath to be as high as it is. They're an incredible pair. I've gotten used to crummy sheaths, but this one is excellent. It has a detent housing that holds the knife secure, allowing you to keep the normal handle snap enclosure free if you want, for a quicker pull. And the detent has a nice thick edge right where your thumb rests, for easy release. The sheath also features a secure velcro fold-over as the belt loop, which means no more having to undo your belt in order to wear or remove the sheath. Lastly, the sheath is reversible so it can be worn on the left or right side, with the knife's handgaurd facing forward or backward however you like. As a leftie, I really appreciate this. The knife itself is as advertised. It's a beast. The balance point is near the index finger groove on the handle, making the knife easy to wield and maneuver better than its weight would imply.

Serious self defense, not a utility/survival knife

Very serious self-defense knife. Dangerous in any strike direction. Excellent quality for price, typical of Cold Steel. Better than I expected. Substantial weight, but remarkably well balanced due to knuckle hardware. Aluminum handle / guard / knuckles are comfortable and very sturdy. Blade was sharp out of the box, but can be sharpened further if desired. Compared to classic Fairbairn-Sykes, knife blade is wider, untapered (except last 2 inches), and more shallow diamond cross section. All points to superior cutter but slight inferior penetration. Grip, for me, is excellent. Surprisingly, is not difficult to grasp or release but would be hard to take or drop. Strange description, I know. but accurate. You must hold for yourself to understand. Any grip adjustments I considered meant upsetting these attributes, so I left it as is. Kydex 'type' sheath sturdy, Ambidextrous(switch around hardware) has holes for attachment hardware- lanyards etc, holds well but use hilt snap. Nylon belt loop and snap adequate but i intend to change them out soon with after market. Get One! I think you will not be disappointed for the price and purpose.

Wow Factor

The Cold Steel Chaos Double Edge is my first Cold Steel product. It looks much larger and impressive than the photos and videos I found online. It is very well made, has a good heft to it, and comes extremely sharp. The sheath is great too. I'm very happy with it!

I called Cold Steels R & D department and mentioned that the back of the male snap that secures the knife handle rubbed off the finish and should have something over the metal to protect finish.

Just another neat item for my collection...

I purchased this knife to add it into my collection. I find it overall to be very well executed. The finish seems like it wouldn't take much to scratch it, and it is applied from head to toe, (from blade to pommel nut). Would have been awesome if it had a matte black anodizing on the handle, and a phosphated finish, (aka parkerized),, on the blade and pommel nut. That said, this knife is definitely an awesome deal at it's current lower price of $50. This is likely it's last year of production, I recommend getting it now if you have ever pondered getting it in the past.

Cold Steel 80NTP Chaos Double Edge

Pros : Excellent knife. The quality is very good, blade is very solid. It's all in mat black, therefore no light reflection which is perfect for night missions. The handle has a very good grip. The finish is excellent, not a single sharp edge or loose screw. The Sheath is also very good. Cons : can't find any, but if you have small hands it might be a bit too big. For me it fits perfectly. The blade is not razor sharp when it arrived but it certainly is sharp enough. You can always sharpen it if you really want to. I was always looking for a Trench style knife. Never found a good one that was not cheap Chinese copy of the original, and this one is just perfect.

Wow... this unit has a great feel and weight. looks very nice. I would consider this a # 1 all around choice for a personal weapon. The sheath is awesome too. After a quick sharpening and a fresh coat of WD40, this thing is ready for serious close combat. The unit is bulky and hard to keep hidden in normal clothes.. so look into special belts/body straps.

The new low price makes it a buy it now situation...

The Cold Steel Chaos series has included six different models, they being the Tanto, Bowie, Kukri, Stiletto, Push Knife, and this model being reviewed, the Double Edged Trench Knife. With Cold Steel being under new ownership, (as of late 2020), there is a good chance that the remaining Chaos offerings, (that being the Trench Double Edged Dagger, the Push Knife, and the Bowie), are likely to follow the other three models that were discontinued. Knifecenter is good about buying closeout clearance goods from the manufacturers, and passing the savings onto their customers. This is what I believe is the case with this knife, the new Cold Steel owners likely discontinuing this model, and the savings is now giving those that have sat on the fence about getting one, a chance to finally take the plunge, and get a great price to boot! If my gut feeling is correct, this model, and likely the rest of the remaining Chaos series, will go the way of the DoDo Bird... They likely to be discontinued and not be seen in the upcoming 2022 Cold Steel catalog. It's a cool knife, and even if for that reason alone you decide to buy one, you won't be hurt much by it's price, and it may be the last opportunity you may get to aquire a new specimen of this model before it disappears from the market :)

HARD TO KILL

This a fighting knife, end of story. It's not for survival. It's not a utility knife. It's not for cutting your steak, batoning, or building a shelter. It's for self-defense and mortal combat. That said, you'll understand I haven't had a chance to use it for its stated purpose yet, and it would be nice to never have to. However, let me tell you why it's such a perfect knife for what it's made for. First, it's a dagger, with a double edge. No flipping the blade to pull back across a body part belonging to a sentry. Easy in, easy out, less drag from a blunt side/edge. The D-guard is the next function I find most useful. Use it to parry, to punch, to break a fall, to protect your hands from your enemy's gear as you slash and stab. The guard is also reinforced by a brace midway down the handle, making you place two fingers on either side. This may appear a pain in the ass at first, but it has a very specific purpose, you ask me, other than keeping the guard strong and sturdy: It makes it that much harder for someone to take the knife out of your hands. Your middle and third finger naturally grip against the brace. Thirdly, the glass breaker on the pommel is a useful, less lethal alternative to using the blade. Smash a temple, a knee, a shin, pressure point, etc. And that's just on bad guys. Use it to crack a nut or break a passenger window once in a while, if you must. Weight is lite and nimble. I have "fighting knives" and this puts them to shame. Sheath is fine. Nothing beats a custom-made job, of course, but blade retention appears more than adequate, with multiple carry options. Overall, the knife feels very, very solid. Nothing feels tacked on. It's a one-purpose tool, and it knows it. As far as blade material, thickness, coating, full-tang vs. partial, grip material, edge retention, etc. I say only this -- that when it comes to daggers, none of the above matter nearly as much to me as they would if I were looking at a survival knife, for example. Let's be honest, daggers get used a lot less than utility knives. Unless you're living in a video game. Which might be kind of cool.

Looks like a reallly good idea for Spec Ops

I am a former Infantry soldier having served in Vietnam as a Scout Dog Handler. 17 ounces might not sound like much, but hour by hour, day by day, the damn ounces add up. Would I rather have 2 and 1/8 cups of water (yes), or 17 oz of 5.56 ammo (yes) or this thing? How many soldiers, sailors, marines, spec ops actually need to stick someone? It does happen, but not that often. If you want a sticker, get one of the new Cold Steel Spikes. This blade would, I am sure, do the job. But at what cost to your back? This blade is for spec ops, REMPS, and people who are too chickenshit and cowardly and yellow and think that THEY are too special to serve their country to actually join the Service, but want to appear to be really, really badasssss to their friends. But since I'm now 66 years of age and shouldn't have to go to the field anymore, unless the ISIS craziness takes over the world, I might get one of these for a novelty item.

This is light

I'm about 110 pounds - 5'6" and some change. Thought this would be heavy, but it's a lightweight juicy thang!! I really can't fathom a greater weapon than the trench dagger, (though this is more of a combination Trench/Yarara) it slashes, thrusts, pierces, and bludgeons. You don't even have to take it out of the sheath for it to be a powerful striker. The top blade will seem worthless at first, but believe me...it's one of the most defensive parts of the "double edge chaos" right next to the dual-section-knuckle-guard. This doesn't come very sharp, so you will have to edge it...other than that - super bada** SK5 construction. Probably won't stay beautiful for very long - but who cares - look at the price-tag!! Barely a WW1 remake, considering most M-1918's weren't used until WW2 and quickly replaced by M3. A weapon lost in time.

BANG for the BUCK.

0 DARK 30: I SILENTLY closed to almost within arms length of the sentry. I reached for my COLD STEEL Chaos with my left hand ... only then realizing that it was not where I usually carried my blade because the sheath was not ambidextrous. Slowly I shuffled hands with my High Standard with the silencer. I went to deftly pull the CHAOS with my right hand, and the form fit sheath held on to the blade like a desperate housewife clings to her charge cards. The sheath finally gave up and with a rather loud SNICK the blade was in my hand just as the sentry turned saying "What the hell was that?"... WITHOUT getting into war stories, I have on occasion in my life time gone in harms way carrying various instruments of war. A blade, a GOOD blade was always a necessity... for all sorts of reasons. Curiosity got to the better of me when Cold Steel introduced this one, as I have handled and used the "real thing" , both WWI and WWII various "trench knives" A friend of mine used to also have a full collection from both wars as well and so I am quite familiar with them. The opening paragraph points to two of the points I would call negative if going in harms way for serious is the reason for purchasing this knife. I have no idea what the engineers were thinking when they did not make the sheath/knife combo ambi, at least it is not to my line of thinking. Let me clear this up. You can carry it on the left side but the handle/grip configuration is all wrong. ALSO.. for a fighting/combat knife the sheath is LOUD. It is NOT STEALTHY. The originals were heavier than the CS version, most using brass or steel for the handle and protection. AND I think CS did not allow for the larger handed of us in this version. A real ham hand will find it somewhat binding, same for cold weather with gloves, but, there is room enough and material enough to open the grip up a little without degrading the hand protection from working. Other than that there is not much else to say of a negative nature. The plus side... Nice weight for all the material there. The finish is consistent and it looks like it will wear well. The new sheath.. well as I intimated above, IT IS NOISY if you are doing silent wet work but most of us, we will never have to worry about that kind of stealth. The only way you will lose this knife is to forget it somewhere. The sheath grabs it and locks on. There is also another loop to secure it with a snap. It is going nowhere. ALSO, there area enough attachment positions on the sheath you could find a way to strap it to anything you wanted. The quality is typical of CS knives. Very good and while not a show knife it has no flaws that I can find. It comes out of the box sharp enough to hurt yourself very easily, it is sharp, but as with any production knife it could stand a little cleaning. I like the Spyderco sticks and after a few rubs with the medium fine I then went to the ceramic, now HOLY CRAP IS IT SHARP!!!!!! It will take a while for the arm hair to grow back. I haven't had a chance to get into the woods with it yet since I just got it a few days ago. AND, neither blade design, double edge or tanto, is what I would really choose to take into the deep and dark, but I should have an opportunity to give it some work over the next few weeks to see how the edge holds and how it works on various tasks. If I was going into a knife fight it would definitely be my first choice(after they said no guns), it offers all the right bells and whistles. If you are not envisioning MORTAL COMBAT and looking for a more general purpose knife, you can buy a couple of CS Bushman knives for the same $$$$ and be better off. It is far cheaper than buying an original after which it is a copy and probably last longer... still... I like it and the quality... Just don't know what I'm gonna do with it now.

Afterthought

Just got the knife yesterday and have not had a chance to abuse it yet! How ever it feels (as most CS knives) well built and solid. It is Nice and Sharp out of the Box. Also the SK-5 steel is a fairly good steel, allthough some tlc and oil is recomended. The only thing I am not happy With is the Choice of handle finish. It is not wear resistant at all, and in fact it had allready peeled of on a small area due to friction from the loop snap. That said I would all in all certainly not have any problems With recomending it to anyone!

I like the knife very well. But blade needs steel upgrade

You either like it or you don't. The only things that I would like to see upgraded is handle grip extended an extra half to 1 inch for larger hands. If you got XXL hands and fat fingers. You may not like the grip. I am an XL size and hand fills entire handle and knuckle guard area. Blade steel is SK5 and roughly equivalent to 1084 carbon steel. Will rust if not kept clean and oiled. They should offer the Chaos line up in a tough Stainless such as AUS8, San Mai, or even D2. Along with SK5 versions. Then set prices accordingly according to the steel type chosen by customer.Kind of like how they offer 2 or 3 steel choices with their SRK series fixed blades. But for the price of $49.99. This is easily a 5 star knife. And very solidly built. However due to Cold Steel using fiberglass in their Secure Ex sheaths. Which dull the knife and refusing to fix or upgrade to Kydex or better material. I dinged a star. So I give this a 4 star rating. If you get this knife. And plan on using it for carry in camping or outdoors activities. Look into a Kydex, leather, or nylon sheath and throw the Secure Ex in the trash can.
