This Kasumi Damascus Sashimi Knife is a long slicing knife that was designed to slice thin slices of fish for sashimi and sushi. Its elegant thin blade is able to slice through an ingredient in long uninterrupted strokes, preserving its integrity and freshness unlike other knives which can damage the cell walls and alter the feel and taste. The main cutting blade of KASUMI knives is made of VG-10 high carbon stainless steel that has been developed especially for knives. The blades are hardened to Rockwell C59-60 degrees, and therefore, keep a sharper cutting edge longer than any other knives. On both sides of the main cutting blade, fine damascus stainless steel pattern is clad. The KASUMI pattern that you see on both sides of the knives is the result of repeated folding and forging of fine stainless steel into multiple layers. Each knife is carefully finished throughout each step of the manufacturing process by the hands of skilled craftsmen. The beauty of the KASUMI pattern together with the strong black laminated wooden handles makes these knives look graceful, yet strong, and good for any style of cooki ng.
