I have (from least to most aggressive) a Razorock SLOC, Razorock Old Type, Fatip Piccolo, and a Razorock JAWS in my rotation, all of which are good, but lately I've been using a Phoenix Artisan Accouterments Bakelite Open Comb Slant most frequently. Unfortunately, the BOSC is sold out on the PAA site and I don't know if or when more will be released, so you'd need to look on the secondary market for one.
