Kai Seki Magoroku Kinju ST Japanese Deba Knife

This model features a traditional single-bevel edge, which is standard for Japanese Deba knives to ensure clean, precise cuts when filleting fish.

While it is specifically designed for fish preparation, the sturdy blade is also effective for tasks requiring precision, such as slicing sashimi or cleaning smaller proteins. Avoid using it on hard bones or frozen foods to prevent chipping the edge.

To keep the handle in good condition, avoid soaking it in water or putting it in the dishwasher. Simply hand wash the knife, dry it thoroughly with a soft cloth, and occasionally apply a food-safe mineral oil to the wood to prevent drying or cracking.

Because it is a single-bevel knife, you should sharpen it using a whetstone on the beveled side to maintain its specific geometry. It is best to avoid pull-through sharpeners, which can damage the edge profile.

Yes, the 150mm length is very manageable, making it an excellent entry point for those learning traditional Japanese filleting techniques. The stainless steel construction also offers more corrosion resistance than traditional high-carbon steel, making it more forgiving for home cooks.
