Or anything like it?

Says it can be use with wensel woodsman type heads even though the blade angle is more aggressive. I've had a few emails with Ed at ABS and he assures me it works well on them, even though he has since developed a 60* angle sharpener for 3 bladers.

I'm more interested in the concept and how sharp these type of sharpeners can get a head. Anyone use one?
