I just got an Izulz,RC-# RP and a RC-6 just before Christmas. I have not checked out the RC-3 & 6 much but I love the Izula. I almost didn't get the Izula because I have a number of knives in this same size. Let me tell you It IS sharp! I'm not talking shaving sharp :jerkit: I'm talking splitting hairs sharp. I can slice hair long wise making curls with it!
