Logan, i use the stone you get in a set at home depot. mostly the large cone, and a flat circular wheel. the cone is great to get your angle for tapering and putting an edge, the wheel is for taking off alot at a time. you really should use a dremel but im lazy and dont feel like paiting forever so i used my high rpm die grinder <img src="/forums/images/graemlins/cheers.gif" alt="" />
