(What is High Speed Steel ?)
The ultimate sharpness that supports the craftsman's skill: High-Speed Steel Grafting Knife
Grafting is a delicate process that involves precisely adhering the cambium layer of a plant. For this, a "sharp cutting edge" that can cut through without crushing cells is essential. This product uses high-speed steel, the highest quality steel used even in demanding industrial settings.
High-speed steel is a special steel originally developed for machine tools used to cut metal at high speeds. It contains a luxurious blend of rare metals such as tungsten, molybdenum, and vanadium, boasting significantly higher performance compared to conventional carbon steel (such as blue and white steel).
Incredible Hardness and Long-Lasting Sharpness
High-speed steel is extremely hard and highly wear-resistant. Even after repeatedly cutting hard branches, the blade edge does not easily become dull, maintaining its superior sharpness for a long period after sharpening.
(Concave processing)
"Concave processing" is a technique used to make the back of the blade slightly concave, improving its sharpness.
This working knife No.7401 , 7402 ,7403 looks the same as grafting knives such as grafting knife, but it is made differently. The back side of a blade is concaved about grafting knife. As you can see from the photo, the back side of working knife is flat.
This technique is mainly used for Japanese knives such as sashimi knives and deba knives.
