Masamoto Sohonten Hongasumi White 2 Deba 210 mm KS2021, Japanese fish knife
This deba is a thick single-bevel fish knife for filleting and cutting through heads and small bones. The blade is a practical everyday length. Forged by Masamoto Sohonten Hongasumi, it pairs hard, keen Japanese steel with the thin grind and balance that let the blade glide through food with less resistance. The forged carbon steel takes a keen edge and gains character with use.

Care and everyday use
It is at its best for filleting and breaking down fish. This is a carbon-steel blade, which takes an exceptionally keen edge but reacts with food and water. Hand wash and dry it immediately after use, wipe on a light coat of oil before storage, and expect a natural patina to form over time. Keep it off bone and frozen food, and sharpen on a whetstone to bring the edge back.

Lovely knife and a joy to use. A little more blade care than my stainless knives but worth it.
