If you mean the liner lock knife with the partial serrated blade I have used one and after I saw how it performed I now have about a half dozen of them.
I shot a buck and gutted it out so fast with that knife. Usually it takes a moment to get thru the hair and started thru the skin. That knife is so sharp that I could see the cut hair jumping left and right away from the blade. It was like one of those Jap steakhouses!!
As a mfg. rep. I have an account with a wholesale house and I can get just about any knife at about half price. These Winchester/China knives are a better buy. They are marked "Surgical Steel" whatever that means! but indeed they are sharp and hold an edge. I have a large knife collection and I prefer one of these knives in case I loose it. On the takeback side they are a liner lock and harder to clean the gunk out afterwards. Those brass rivets and wood inlays sure look nice to me. Yes they are $9! You don't get what you pay for. You get what you know and work for.
