I've used the tamer for alot of years and let me tell you, I'll put the blade sharpness up against any sharpner out there. I know thats a bold statement but it's true. Like Ben said, take a little from the tip and they are solid. I recently purchased an expensive flat file on here and cannot get them as sharp as I do with the tamer. The lack of hair on my forearms shows just how sharp they get with very little effort. Once I change the angle, it takes less than a minute to resharpen a BH.
As far as durability, ask Paul Brunner. When their shop was in New Kensington, Pa. they tested the Snuffer that had been sharpened by the tamer. It went into a cinder block. Beside the tip(which needs taken down a touch) the BH held together. Not certain bone is as tough as a concrete block. You get the point.
Terry, yes, the WW will work on the tamer. It will change the angle but they will be scary sharp. The leather strop is the final key. There are other methods out there I have read about, but none that is as simple and in less time than the tamer. Well, theres my 2cents.
