Buck Zipper Guthook Wood 2550The Buck 191 Zipper Knife is a beautifully crafted gut hook hunting knife that blends traditional style with modern performance. Designed in 1993 by CJ Buck to outperform the subpar gut hooks of the time, the Zipper was built to live up to the Buck family name. Its razor sharp 420HC stainless steel gut hook blade, combined with the ideal edge angle and hook length, makes field dressing big game fast, smooth, and precise, working just like a zipper.
