About Masamoto Ao-Ko Hongasumi
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. Blue steel #2 is a mixture of chromium, tungsten, and white steel #2. The addition of chromium and tungsten to white steel gives it added hardness, making it a good compromise for those who want a carbon knife with a longer edge retention.
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.
