I've been reading the positive reviews of the Dorko 300, and it's similarity in shave to the Le Grelot 1/4 grind. A couple of questions about the Dorko ... Is it a 1/4 grind? Also, is it a 6/8 or 8/8 blade, or both? I'm asking because I don't know if a Dorko 300 comes in various forms (grind, blade, etc.), or if it comes in only one format. Thanks!
