Hidetsune Kurouchi Ryo-Deba 150mm
Ryo-Deba – Traditional Fish Butchery Knife
This ryo-deba, a double bevel version of the knife traditional deba, is a robust, Japanese knife designed for breaking down whole fish. With a thick spine, heavy weight and strong heel, it excels at tasks requiring controlled power — such as removing heads, cutting through small bones and filleting with precision. Despite its strength, the fine edge allows clean, accurate cuts, making the ryo-deba a staple for anyone preparing fish in a traditional Japanese style.

Kurouchi – Rustic Blacksmith’s Finish
Kurouchi is the dark, textured finish left on the blade from the forging process. It helps protect the steel from oxidation while giving each knife a unique, hand-forged character.

Steel Care
• Always hand wash immediately after use — never in the dishwasher.
• Dry completely with a towel to prevent rust or discolouration.
• Use wooden or soft plastic cutting boards to preserve the edge.
• Store safely in a block, on a magnetic rack or in a saya cover.
• Sharpen regularly on whetstones for long-term performance.
• Carbon steels will form a patina over time — this is normal and protective.
