Long DescriptionThe Buck Zipper Knife, like its name suggests, is a guthook knife that works just like a zipper. The combination of edge angle and hook length perform beautifully together. Back in 1993, there were a lot of guthooks on the market that just didn't do the job right. So, CJ Buck, a 4th generation Buck family member and current CEO and President, helped to design a knife that would live up to the family name. Overall length: 8 1/2" (21.6 cm). Imported sheath.
