The historical Roach Belly knife was a short blade with a pronounced upswept curve and a sharp point. Cold Steel’s version retains the profile of the original but incorporates the latest in modern materials for its construction. The hollow ground blade is made of 4116 Krupp Stainless, expertly heat treated to Rc 56-57, and has a fine, sharp edge that’s easy to maintain. This knife is made with a Polypropylene handle and comes with a Cordura sheath.
