Why Are Japanese Fillet Knives Best?
Japanese vs. German Steel
The main types of steel for knives is either German or Japanese. The key differences of the steel are hardness, tang, sharpness, and in their durability.
Hardness is measured by the Rockwell Hardness Scale (HRC, or Hardness Rockwell C). German steel usually measures up to 55-58 HRC, whereas Japanese steel often exceeds 58-62, significantly harder. Tougher steel stays sharper for longer, but softer steel is easier to sharpen.
Tang refers to how far the steel blade runs into the handle. A knife with full tang will have the steel run from tip to the butt of the knife, most often observed in German steel knives. Partial tang will have the steel running only partially entering the handle, is many Japanese steel knives.
Sharpness is just how thin the edge of the knife is and what degree it’s sharpened at. Always use a sharp knife, as it makes everything easier and you’re actually more likely to injure yourself when using a blunt knife. Japanese steel knives are usually sharpened at the 15-degree mark, whereas German steel is often around the 20-degree mark.
Because of these qualities, the Japanese fillet knives naturally perform better than other knives for cutting, slicing, and filleting fish. This is true no matter what type of Japanese filleting knife you are comparing, whether it’s a boning knife, Japanese fishing knife, or a Deba Knife.

Deba Knife Vs Fillet Knife
The Deba Knife is much wider and less flexible but is much more versatile in its use. Designed for both beheading and filleting allows you to be more efficient when filleting your fish from start to finish.
However, when it comes to filleting large fish, the Deba knife often doesn’t have the length and flexibility to maneuver as swiftly as the other “boning knife” style Japanese fillet knives. Further, the blade is not as thin, which can make precise cuts a little harder.
The standard style fillet knife does fillet fish in a more efficient, elegant, and effective way than the Deba knife. But, it does depend on the size and type of fish you are filleting. Filleting larger fish sometimes even requires a knife longer than a classic boning knife or Deba knife, which is where a Yanagiba comes in handy.
Features Of A Japanese Fillet Knife To Look For
Traditional knives are more likely to have a stiff blade. This is great for cutting most meats but not ideal when you’re trying to slice the meat off the delicate fish bones. The best Japanese knife for filleting fish offers a thin, flexible blade that can slide underneath the meat, and bend slightly helping you make a precise cut. Unlike a standard knife, which can get caught in the meat and result in jagged edges, a high-quality Japanese fillet knife should glide effortlessly through the meat as it separates it from the bone.
If you plan on cooking a lot of fish, you might want to have multiple Japanese filleting knives in your arsenal. A large knife works great for larger fish, naturally. But, if you are cutting a lot of smaller fish, a knife with a shorter blade makes things so much easier. The rule of thumb to follow is to use a knife about as long as the fish.
Japanese filleting knives are some of the sharpest in the tool shed. They also tend not to have a full bolster either, which would usually keep your fingers much safer. So make sure you find out what kind of handle the knife comes equipped with, particularly when shopping online, as it’s vital to find one that has a strong no-slip handle with a good grip.
Single vs. Double Bevel
Single and double bevel refer to the knifes blade having either a one-sided, or two sided angle toward the edge.
Single bevel is best for filleting most fish, as it’s must easier to get a precise cut. When you are filleting fish you can lie the edge of the knife flat and make a clean horizontal cut to get the fillet.
Double bevel is more for general purpose, and won’t make as precise cuts as a single bevel knife. This isn’t always a problem, and depending on how exact you want your fish fillets, a double bevel knife will do just fine, but a single bevel will help get you to that professional quality precise cuts.
Maintaining Your Japanese Knives
You can go on and on (and on) about caring for your Japanese knives, but kept simply, you just need to keep them sharp, honed, and stored well.
Keep It Sharp
Using a sharp knife is essential. As japanese knives are usually hand sharpened during manufacturing at a 15-degree angel, be sure you either get a high-quality 15-degree automatic sharpener, or put the effort in and use a whetstone to be more precise.
Keep It Honed
The last thing you want is scratches all across the surface of your attractive Japanese knives. The best honing steel for Japanese knives are always ceramic and very fine. You have to be extra careful if you decide to use a steel honing rod to hone your steel not to damage the blade edge.
Keep It Stored
Most high quality Japanese knives come with either a sheath, or a box with padding. Take full advantage of these, as they usually fit perfectly snug against the knife protecting it as well as possible.
