This is a Masahiro Usaba traditional Japanese sushi chef knife made in Seki Japan. In excellent condition, unused by the consumer but there is some rust, tarnish spots and light scratches on the blade, please see pictures. Comes in original box. The Usuba is the choice accessory vegetable slicer for the sushi chef. The knife is sharpened on one side to form a single bevel edge with a slightly concave flat grind on the opposite side for a more precise and uniform cutting edge. The hand forged 195mm blade (just over 7.75") is made of Hitachi Kiigami Hagane Carbon steel (yellow steel) laminated with soft iron to form a superior kitchen edge. The handle is made of Japanese Magnolia wood with black resin bolster.
