Just yesterday I was playing around tuning a few bows with broadheads. Sharpened some Bear greenies with a file and some Zwickeys and Stingers with the AccuSharp. I pulled out an old blue stainless steel 145gr screw-in Bear Razorhead. Use to shoot them for summer broadhead leagues through cardboard animal targets into sand piles. A summer of sand will dull one up pretty darn good. Put one of those "butter knife" sharp buggers on an arrow and in about two minutes I had it shaving sharp with two AccuSharps. One I use for heavy work and the other for light finish work. They work like a charm.
