Product Description
The Buck 691 Zipper Guthook is a purpose-built hunting knife designed to open game cleanly and efficiently. True to its name, the guthook works like a zipper, using a carefully engineered hook length and edge angle to glide through hide without damaging meat. The 4.25" blade is made from Buck’s 420HC stainless steel, heat treated for reliable edge retention and easy sharpening in the field. Designed with input from CJ Buck, a fourth-generation Buck family member, the Zipper was created to solve the shortcomings of earlier guthook designs. The rubber handle provides a secure, non-slip grip, even in wet conditions, making this knife a dependable tool for hunters who value control and performance.
