KME with diamond stones and the stropping leather with various micron stropping conditioners is what I use for knives and broadheads. I used to be able to get stuff sharp, but sometimes it took me a while to get there. The above system takes ALL the angle guesswork out of it for me and while it was an initial investment, now going into the second year, it's just touch-up on those that I ground to the angle I wanted last year.
If you're doing any kind of bevel reworking, you're going to want the course diamond stone in your arsenal, otherwise you're going to get frustrated.
