Whoa...that's a lot more intense than I thought it was going to be. Impresive. I had a passing thought that it would be cool (though cost prohibitive) to use two spyderco bench stones layed at an angle against something , with a barrier at the feet to keep them from slipping, to greatly increase surface area for sharpening and reprofiling. But this is next level. Thanks alot for the quick response. I wasn't expecting to hear back for days, if at all. Really helpful.
