Reforge: Melk the Second
|[v · t · e]|
The Derous Kitchen Knife is Komatsu's pride and joy and his main cutting tool when preparing all his dishes. It was originally used in a set with Komatsu's other knives but now stands out as a unique tool of its own. Though originally not anything special, simply a normal knife like the others that Komatsu managed to buy by scrounging up his savings when starting his career as a chef, his great care and love for it truly made it something special. It even caught the eye of Starjun, a sous chef for the Bishokukai.
After Toriko's return from Gourmet World, Komatsu breaks this knife while attempting to cut a Don Acorn. The broken knife is eventually repaired by Melk the Second using a piece of Derous Fang. The knife is so hard and sharp that the only way to shape it was by slowly grinding it down with Melk Stardust as no amount of heat or hammering would affect it, and once finished, a light swing of the knife cut an entire mountain range in half. Upon finishing the knife, Melk the Second, for the first time, etched a personal signature into one of her knives. It is so sharp that Sunny commented it would have sliced him in half if he tried to hold it with his sense of touch.
