This is a MINT prototype of Reese's new model, the Shark. It has a perfect double flatground 3/16" S30V, deep blade with ambi thumb disc. Thick titanium framelock with extremely smooooth action, rock-solid lockup, and tip up concealment clip. The OAL is 8 1/4", with 3/34" blade - a nearly perfect blade/handle ratio! Boat tail butt is useful in non-lethal applications, too. Never carried or used, razor sharp, marked "proto" inside the steel spacer. Asking just $old.
