B Knife

B Knife (Presumably Butcher Knife) can be found on Melvin's body at The Hole in Chapter 7, or brought from the all in one weapon shop at The Hole when unlocked. The strongest of all the the knives. Apparently increasing Attack and Technique stat will increase the damage done with a knife, but that is unproven so far. The only character known to carry a B Knife is Melvin.
