Heretic Koschei Marble Carbon Fiber

The Heretic Koschei Marble Carbon Fiber is a manual folding knife, not an OTF. Koschei is Heretic's first crossbar lock design, and this custom build dresses it up with a high polish DLC blade and marbled carbon fiber scales.

Dealers listed this piece as a 2026 Blade Show special. The black DLC blade has been polished to a deep shine, and the DLC hardware keeps the whole knife dark and clean. The marble carbon fiber shows swirls of gray and black that change with the light.

It opens with a thumb window and closes with a crossbar lock you can work with either hand. The clip is reversible. That makes it an easy carry for left- or right-handed users who want a gentleman's folder with real working steel.
