The TCK 2.0 Slipjoint

This ultra-thin blade will out-cut any steel knife on the planet.

Sharper, thinner, and harder than any blade ever crafted, TCK is an ultra-thin Gentleman’s Folder suited for everyday carry. Equipped with our patented Polyhedral Tungsten Carbide, which boasts a Rockwell Hardness of 71 HRC, the TCK vastly outperforms steel. Scientifically proven to hold a sharp edge longer than any other knife, the TCK may be the last EDC you will ever need. It is designed to cut and cut, and then cut some more.

The 2.0 is an evolution of our original TCK, a proof-of-concept knife that the industry thought impossible. The new TCK 2.0 features slip-joint construction with stainless handles finished in a black vapor deposition and accented with a red liner for a touch of style. The blade is mirror polished and finished in a black Diamond-Like-Carbon (DLC) finish. The two-handed opening mechanism is aided via the Fibonacci-inspired holes in the blade.
