ADKAD205SF: AD20.5 Folding Knife - Shark Foot

Demko Knives

The AD20.5 by Demko Knives features the impressive Shark Lock and an even more impressive price point. After handling a plethora of MG AD20s, we can safely say that this is a very dutiful representation of that awesome mid-tech design. It's slightly smaller all-around and definitely thinner, which makes this much more suited for everyday carry than tactical encounters. The Shark Lock mechanism is situated on the spine of the knife and operated with a ramp-like ‘fin’, allowing you to flip the blade open and closed at will. It's probably the best thing about this knife and design, how quickly it can be deployed and ready for action. It acts as a blade launcher and a little wrist action is all it needs. The AD20.5 is available in two variations, a clip point and a shark foot sheepsfoot, and we really can't think of a way to improve either one. The AD20.5 is incredible.

My other knives are feeling neglected
Since I received this knife 3 months ago, it has not left my pocket. Perfect size, weight, and shape for EDC. My other knives are starting to feel a little neglected. Some people complain about the knife being overpriced for the material used. All I have to say is put one in your hand, flip it open and close 1000 times, and you will feel that the knife is worth every single penny. AUS10A works just fine for me as I don't use this knife for any heavy duty work. That's what the 4max Scout is for (which interestingly is also AUS10A). I only use this knife for light to medium duties such as opening boxes, breaking down cardboard, and cutting the occasional fruit. Other than stropping it three times a week, I haven't had to sharpen it. My only gripe is that I don't know what to do with my other knives!Hope this is helpful.

AD20.5 sharksfoot
I have been anticipating the AD20.5 ever since I first heard about it and ended up grabbing the shark foot version from the secondary market because i know the drops will be small batches and snatched up quickly. Demko knives is not Spyderco and just cant produce the Quantities on that level. The 20.5 is an ideal daily EDC size in comparison with the full size AD20 that is as large as the AD15 i own and not something I would carry most likely on a daily basis and imagine most other people wouldn't either due to large size and weight. The 20.5 is 3.5 oz, thin in the pocket (.380” thick handle), carries great, and has plenty of handle real estate for most hands to get a full 4 finger grip and enough blade length/cutting edge for whatever one may need to do. From what ive read the clip point version has 1/8-1/4” more blade length but the sharkfoot is plenty also so get the shape you like unless you have legal restrictions then the shark foot will meet 3” blade laws. The 20.5 is well built and could handle hard use or edc chores no problem. The shark lock is neat and very fidgety with great action on ball bearings if you care about that which im sure anyone looking at this knife is. Think of a more robust and reliable BM axis lock with a Different deployment aperture and a similarly softer than average detent due to that type of design. Demko stated the lock is as strong or maybe stronger than a triad lock and was tested to 250 pounds of weight hanging from the handle (think cold steel) and 750 inch pounds of torsional force which is more than any hand could generate. The blade had a nice stonewash finish to hide wear and came pretty dang sharp with fairly even bevels on my example. Deployment via thumb stud or opening aperture work well and are easily finger flickable from either side. A truly ambi design and comes with a lefty pocket clip as well. Ive heard they are made in the Cold Steel factory which seems believable with comparable good fit and finish, Zero blade play, and good centering. The packaging is very nice if you care about that with a nice box, soft lined zipper pouch sporting 2-3 pockets with a velcro sharklock patch on top and a micro fiber cloth. Some call it the WE knives treatment lol. There are full stainless steel milled out liners to support the FRN scales which are made in the same texture pattern as the full size ad20 and offer good grip without being too rough imo. The clip has a matching SW finish and works well with good retention. It is not a deep carry so maybe a half inch sticks out the pocket which is fine with me and no hot spots from it which is more important. Only gripes which are really nit picks would be the shark lock can be a little sharp after repeatedly flicking it. I may lightly file the jimp on the corner but its not a huge deal really. The other is the blade is thickly ground behind the edge but it is designed for hard use and imo most knives are too thick bte anyway so i could say that for almost every knife lol. It does cut well though thanks to a keen factory edge. The materials don't blow my socks off but are plenty adequate and Andrew Demko stated they will be doing different colorways and s35vn steel later this year on the 20.5 most likely but with an increase in cost due to machining processes involved for a PM steel. This version is the entry level model which im happy with for now. Think of AUS10A as 154cm junior as far as edge retention and ease of sharpening. It is not the lesser AUS8 steel which some confuse it with and is Significantly better than that. fingers crossed G10 will be an option also or at least the aftermarket starts offering scales but the FRN isn't bad at all and super durable. Overall its a cool innovative practical folder and one i would recommend.

Disappointed
The only reason I'm giving 3 stars is because the action is pretty addictive, very unique. First thing was the factory edge, had burr leftover and little nicks the whole length of the blade. I always sharpen a new knife immediately so that wasn't a huge deal but would be for someone that doesn't sharpen their own knives. Started to re profile because at 28° per side it didn't cut great. Noticed that one side was 28 and the other was 32 degrees, totally unacceptable for a $150 knife. Then I noticed that the primary grind was off and that's probably why they did such a bad job sharpening it at the factory. The thumbstuds are supposed to be removable but only one side has a notch for a flathead and it just free spins. I really wanted to love this knife but it has Way too many mistakes for $150
