This knife was custom made by me on a CNC machine in my home shop. I am a new knife maker and this is my second knife, the Model 2. It is a flipper style knife. The knife handles are made from Ti-6Al-4V Titanium. The blade is 154CM and has been heat treated with cryogenic treatment. The blade rides on hardened 440C stainless steel caged bearings and hardened stainless thrust washers. The pivot and pivot screw has been made from 416 stainless and has been hardened. The knife is a frame lock with a hardened lock bar insert. The knife has a milled pocket clip that is made of Titanium. The knife is 4.55 inches long closed, 1.0 inches wide and .500 inch thick with a .125 inch thick by 3.25 long blade. The knife weighs 4.0 ounces. The knife is 100% American made.
