Currently i only use my own knives. Trying to test their qualities as far as edge retention , blade design ( which is pretty classical although I have experimented a bit with blade and handle shape I really like the handles on some of the Globals, as well as steel thickness ) I do have many Global, Shun ,JA Henckels , Wosthof , nothing super fancy , just good hard working knives. I have always been a hard sharpener up until I started making my own . Not starting with a factory edge its hard to tell exactly what the angle is. When I started reading about the Wicked Edge , I was sold. Cant wait to get my PP1 I plan on starting with my home knives which the wife uses, then the Wosthofs which my cooks use, working my way up to mine. The learning curve thing sounds like a good idea. Thanks for the welcoming messages. I hope to be able to offer any help I can.
