"Fantastic shop! Very helpful and has a good variety of Knives, Axes, and Accessories. They were able to reshape one my old knives that I’ve had for about ten years. The tip broke off a couple years ago by another person that used it. Now the knife looks like it had never happened. Definitely will be back for a new fixed blade when it gets closer to hunting season!"
