Back in 1993, there were a lot of gut hooks on the market that just didn't do the job right. So, CJ Buck, a 4th generation family member, helped design a knife that would live up to the family name. That knife is known today as the Buck ZipperTM. And just like a zipper, the edge angle and hook length perform seamlessly together, making it an ideal tool when field dressing game. The drop point gut hook uses 420HC stainless steel that's steadfast and sturdy for the task at hand. It's finished with Buck’s Advanced Edge2x blade technology that offers a lasting edge retention for the long haul.
