yeah that is what i started using too. you have the one on a grinder or buffer right? that is kind of the bitch with 2 blades at times. clotting or debris in the wound channel can stop the flow up some.
Holy shit. I use the same sharpener when I'm in a pinch and don't have time to do it on a stone. We keep one of those down in the skinning and quartering cellar. Gets a knife razor sharp in only 3-4 passes.
