ADKAD205SFD2OR: AD20.5 K110 (D2) Shark Foot Folding Knife - Orange
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 so we had Andrew make us a few of our own. The AD20.5 is incredible.

Seems like a very well regarded knife, and $75 is a steal compared to other sites selling the same knife. I don't like that it's D2 but, not all D2 is created equal. Depending on manufacturer, D2 is either garbage or fantastic and close-ish to S35VN.Denko is pretty highly regarded so I'm going to err on the side of this being a pretty damn good value.

Andrew designed many of Cold Steel's knives. I met him a knife show several years ago. Really great guy. Really great knives. I own so many, not sure the count

The Cold Steel AD-10 is a must-have Demko designed knife. Always been wanting a proper Demko for the right price. Apparently the dark earth grivory color is known to be different than the Kc product photos. A lot of reviews say it's too expensive for the materials, but this price might be right for possibly the strongest lock up tested in the industry and a fan favorite for fidget factor from one of today's best knifemakers. Also, big fan of Knifecenter.
