Hitohira Hiragana Deba 120mm Pakka Handle (No Bolster)

The traditional Japanese fish filleting knife. A very old knife shape used for breaking down fish and often poultry. Very efficient in filleting due to their single bevel geometry designed to be strong, reduce friction and have a very keen edge. While it takes a small adjustment in technique the results are often much better compared to using a western filleting knife. Strong enough to cut through fishbones and a much sharpen edge resulting in higher quality cuts essential for taste, texture and quality of the produce. 

Stainless steel gets its name from the inclusion of chromium (10-13%) in the alloy, which forms a protective film that helps prevent rust and corrosion by acting as a barrier between the metal and oxygen.
While stainless steel knives are practical, functional, and easier to maintain than carbon steel, they are not completely maintenance-free. With improper care, they can still rust or develop pitting—after all, "stainless" does not mean "stain-free."

The level of corrosion resistance varies depending on the type of stainless steel used, but the basic principles of care are similar to those for carbon steel knives.

To maintain your knife, store it clean and dry, avoid air-drying after washing, never use the dishwasher, and steer clear of cutting extremely hard items like frozen food or bones.
The key advantage of stainless steel over carbon steel is a greater margin for error—its rust resistance is higher, making it easier to maintain with less worry.

Remember, not all stainless steels are the same. Just like with carbon steels, each stainless steel alloy has its own unique properties and performance characteristics, and should be judged individually.
