Vintage Nara Senjuin Deba Knife 180mm Carbon Steel 2298

Experience the Power of the Deba - Nara Senjuin 180mm Carbon Steel

The deba is Japan's fish butchery knife - thick-spined, single-bevel, and built to break down whole fish with authority. This 180mm example from Nara Senjuin is a serious working blade: heavy enough to cut through bone, sharp enough to fillet with precision, and made from carbon steel that takes and holds a professional edge.

Heritage and Character

The deba is one of the most demanding knives to make well - the thick spine must transition smoothly to a thin, hard edge capable of precise filleting, while the single-bevel geometry requires exacting heat treatment to prevent warping. Nara Senjuin's carbon steel deba at 180mm sits at the standard professional size for medium to large fish: capable of handling whole snapper, salmon, and similar species from head to tail. Carbon steel in a deba is non-negotiable for serious Japanese fish work - it allows a level of sharpness that stainless equivalents cannot match, particularly on the delicate belly cuts that distinguish professional butchery. A knife for cooks who work with whole fish and demand the right tool.

• Dry immediately after use to prevent rust
• Single-bevel blade - sharpen on the flat face only using Japanese water stones
