Masahiro Traditional Carbon Knives
These traditional Kasumi style Japanese Knives are true one-sided knives. This means that the blades are fairly thick, and the back side is concave. This allows you to sharpen the face of the knife, then flip it over and lay the knife flat on a stone to remove the burr. Due to the concave shape, only the spine and edge will touch the stone, so you will not scratch the back of the knife. Deba’s are the work-horse of this series used for filleting fish and general purpose work. Yanagiba’s are for slicing meat and fish, while the Usuba is used for vegetable preparation.

Masahiro Traditional Carbon Yanagi 330mm
The Professional’s Standard for One-Stroke Sashimi Mastery When working at a high-volume sushi station, the difference between a good cut and a world-class presentation lies in the length of the draw. The Masahiro Traditional Carbon 13-inch (330mm) Yanagi is not just a knife; it is a specialized instrument built for the 'one-stroke' technique. At 330mm, this blade provides the necessary runway to slice through large loins of Maguro (Tuna) or Hamachi in a single, fluid pulling motion. This prevents the 'sawing' effect that damages the delicate cellular structure of the fish, ensuring a glass-like surface and superior mouthfeel. Crafted from Yellow Paper Steel (Kigami), this blade offers a pure carbon steel experience. It sharpens to a surgical level of keenness that stainless steels simply cannot match. The traditional Urasuki (concave) grind on the back side creates an air pocket during the cut, significantly reducing drag and preventing the fish from sticking to the blade. This is a tool designed for the professional who demands precision during a 12-hour shift where speed and aesthetic perfection are equally weighted. The 330mm length is specifically chosen by senior sushi chefs because it allows for the processing of larger species without repositioning the knife. While a 240mm or 270mm Yanagi might struggle with a thick sakudori (block) of tuna, this 13-inch powerhouse glides through with ease, making it the definitive choice for fine-dining environments and busy sushi bars.
