Suisin Ao-ko Suminagashi

酔心 本霞 • 墨流し青二鋼

The flowing pattern in hand-forged layered steel can be mesmerizing but the advantages of suminagashi (sometimes called Damascus Steel) extend well beyond its beauty. To create these exquisite sashimi knives, craftsmen join carbon steel with soft iron in the kasumi method, then pound and fold the steel eight times on each side. This is a lengthy process, taking as long as needed to make eight kasumi knives, but the end result is a stunning 16-layer blade with the strength and flexibility of a honyaki knife.

For Left-Handed Customer
