Thanks for the information and the link very usefull information.

First time I shaved with a knife was more of a joke. I grew up on a farm an went to a nerd type school lots of hillbilly jokes so I shaved with my hunting knife a couple times. It wasn't particularly painful but it wasn't particulary comfortable. Then I ran out of blades for my razor and had a almost fatal case of sticker shock.

Anyway to get a completely comfortable shave I had to make major changes to the grind.
