Earlier this week I received my Lansky sharpening system, and I love it. I've been playing with it a bit, and managed to get even a cheapy no-name blade razor sharp. I need to put a new edge on my CV Sodbuster Jr. This is my work knife, and sees a lot of box busting, cutting vinyl wallpaper, etc. I was thinking about redoing the edge at a 300 angle. Any opinions?
