About Masamoto Shiro-Ichi HongasumiWhite steel #1 is the purest form of carbon, making it the closest material to Japanese tamahagane steel, which was originally used to craft Japanese swords. Forging a knife out of white steel #1 is extremely difficult and very few highly skilled craftsmen are still able to forge kitchen knives with this material, making knives made out of white steel #1 exceedly rare. Hongasumi knives are high-grade kasumi knives. They are forged, tempered, and finished with great care and precision. To create these blades, high carbon steel is layered with soft iron then forged and hammered in a process similar to kasumi knives but with more detailed steps involved.
Minosuke Matsuzawa, the founder of the Masamoto Sohonten Company started making knives in 1866. It was his dream that his family would come to be remembered as knife craftsmen throughout the generations. Now, five generations later, Matsuzawa’s vision has been realized and professionally crafted Masamoto knives have become widely regarded as the finest knives made for professional use.
Purpose of Yanagi
The yanagi is used to slice boneless fish fillets into sashimi and toppings for sushi. The graceful, long and thin blade is designed to cut slices in one drawing stroke, which applies minimal pressure on the flesh of the fish to avoid stress and cell destruction. Different cutting techniques are used with the yanagi to enhance the aesthetics and the flavors of the fish. There are several variations of fish slicers that are all used in different situations and regions, however the yanagi style is the most widely used. Originated in Kansai (Osaka) region.
