Our Japanese Gyuto and Petty Knives are laminated kitchen knives with a hard cobalt steel core and layered stainless cladding. We carry two petty knives, 80 mm and 105 mm, and a 180 mm gyuto.
The gyuto is the Japanese chef's knife, for slicing, dicing and chopping, and the petty is a small utility knife for paring and detail work. Each blade has a high-carbon cobalt steel core, tempered to Rockwell C63 and forge welded between layers of jigane: two kinds of stainless steel folded together into 16 thin, alternating layers. The cobalt and manganese in the core add durability and make the edge easier to sharpen, and the layers give the blade its look. The Pakka wood handle is riveted to a full-length tang. They're made for restaurant work and heavy home use.
