Shawn -- Ron may slice my throat -- Swishhhhh! --for saying this, but ... I have both the KME broadhead and knife sharpeners, and both are superb, best I've found in a long lifetime of looking (I'm sharpening-challenged). So, while I agree with all amigos above re the KME broadhead rig's excellence, if you're poor like me and also have knives to sharpen, thus can afford only one great sharpener in your life), there's plenty of testimony including my humble own that you can get really sharp heads with the knife rig and a bit of stropping (Ron recommends corrugated cardboard, stropping across the grain), which you can also use for ... knives! But not vice-versa. Also, the knife sharpening jig works great for convex heads like Eclipse, as well as straight. If you can afford both, get both. If not, go for the knife jig. My 2,000 cents worth. dave
