Andrew Demko has been building knives that do things other knives do not for a long time, and the Shark-Lock is the clearest example. The AD20.5 is his production version of the flagship AD20 mid-tech, built around the same patented locking mechanism. The Shark-Lock is a spine-mounted system operated by a ramp-like fin on the back of the blade. Pull the fin back with your thumb and the blade opens; the fin then doubles as a jimped thumb ramp when the blade is deployed and locked. The sequence is designed to be fast, ambidextrous, and to keep your fingers out of the blade's path.

The 2.88" Slicer Shark blade is CPM-3V tool steel with a stonewash finish. CPM-3V is not a stainless steel. It is a powdered tool steel developed for toughness, edge retention, and resistance to chipping under hard use. The recurved Slicer Shark profile maximizes belly and cutting length in a compact footprint, with more cutting surface in a shorter overall length than a clip point or drop point would provide. A ball bearing pivot, thumb pull, and lanyard hole complete the build.

The handle is milled titanium, precision machined rather than surface treated, with contours and texture cut right into the material.
