Best Japanese Fillet Knife of 2023

best japanese fillet knife

Filleting fish is always fun and games until you use the right knife because not every knife is for filleting. Professionals generally use either Japanese or German knives to fillet fish. The best Japanese fillet knife is different from a German knife considering the shape and blade features. And I am biased towards using Japanese knives due to their high-quality and amazing craftsmanship.

To find the best Japanese fishing knives, I usually opt for the one with a combination of flex and a stiff blade. And most importantly, I find the sharpest Japanese knife with a 6-7 inches long blade and a complete slip-proof handle. However, a single-bevel (blade sharpen on one side) Japanese knife is more precise at filleting than a double-bevel blade. So, choose the knife wisely.

After thoroughly researching the Japanese fillet knives available in the market, I tried several Japanese knives for fish. And considering all the above features and my personal experience, I have shortlisted the best Japanese steel knives. The Yoshihiro Shiroko Deba knife is our top pick and best japanese fillet knife among all these knives. Because the knife has every quality of the best Japanese knife, if you’re in a hurry and can’t read the complete reviews, you can trust this one for its unmatchable features.

Buying Guide For Best Japanese fillet Knife

Japanese knives are more expensive than other knives. Here is what you should look for to get the best Japanese knife at a fair price.

1. Blade Flexibility

Japanese blades have a high ratio of carbon which makes them less flexible. However, many Japanese fillet knives are stiff and flexible at a time. So, it is better to find one of that type.

2. Blade length

Japanese filleting knife has a blade size range of 6-7 inches which is smaller than other fillet knives. But the sharpness and quality of Japanese steel make the knives perfect for all fish sizes.

3. Handle

Handle material matters when filleting a fish because of its slime. If the handle material is not slip-proof, your safety is at risk. So, choose the knife with a non-slip and comfortable grip (preferably wooden) handle.

4. Double or Single-Bevel

Most traditional Japanese knives are single-bevel (blade sharpened on only one side). Single-beveled knives help in making precise cuts effortlessly and are incomparable at filleting. However, some Japanese knives are also double-beveled, which is not wrong; you can opt for the one you prefer.
