The Masamoto Ao-ko Hongasumi blades are crafted from a combination of blue carbon steel #2 and soft iron steel. Blue steel #2 is created by mixing chromium and tungsten with white carbon steel in order to produce a blade with longer edge retention than white carbon steel blades. The forging process includes several extra steps and requires a higher level of craftsmanship than kasumi style knives, which gives hongasumi knives a more refined finish.
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.
CAUTION: Moisture Causes Rusting and Discoloration
For Left-Handed Customers
- Left-handed blades must be special ordered from Japan, and will cost 50% more than the right-handed blades. Due to how each traditional Japanese knife is handmade by right handed craftsmen, it will take 4 to 6 weeks to forge and deliver.
General knife care tips and warnings
- Never wash knives in the dishwasher
- This is not stain resistant. It will rust and discolor after cutting acidic ingredients or if one leaves it wet.
- Improper care will result in chipping.
- Please wipe knives dry after use to prevent rusting. Korin recommends wiping carbon knives with tsubaki oil to keep moisture off the knife.
- Western style knives sold at KORIN have significantly thinner blades than typical Western knives. Use of honing steels or sharpening machines may result in chipping.
- We advice all customers to always use sharpening stones to sharpen or hone knives.
Please be cautious when inspecting carbon knives with wet hands after purchase. We ask customers to inspect all knives prior to using, and will not accept returns on damaged goods. In the event you receive a rusted knife, please call customer service within 48 hours, and we will be happy to assist you.
