Well I'm here to tell you, the Snuffer Tamer is an excellent product. I've been sharpening my snuffers since it first came out and have NEVER, hear me, NEVER had a blade fail. Unless of course WHEN it passes through my game and smashes a boulder. I can't tell you the number of times I've shot a deer and went home and resharpened the same head. I just buried one in a tree the other day and after I dug it out, I would have still hunted with it. I hear alot of people dogging the tamer on rumors, not experience. I know what the company recommends, and I respect their intelligence. I'm telling you from my years of using this product that it works. If it weakens the blades, then I don't notice it. There are several ways to sharpen the snuffers, this one is mine. It works and it kills, period.
