What’s the best handle or grip for a fillet knife?

Frequently Asked Questions (FAQs)

What is the best steel for a fillet knife?

Type of steel decides the durability and efficiency of a fillet knife. Both stainless steel and high carbon stainless steel is used in making some of the best fillet knife around the world but the later takes the cake in this regard. Fillet knife made from high carbon stainless steel is considered the best because it stays sharper for longer than stainless steel. Besides this, the high carbon stainless steel knife is harder and easy to sharpen. This is one of the reasons why professional cooks use carbon steel knives. 

What size fillet knife should I buy?

It is more a question of preference rather than compulsion. The size of the best fillet knife depends on the user and the size of fish for fillet. Generally, fillet knives are available in standard sizes of 4, 6, 7.5 and 9 inches. So if you want to fillet panfish then 6 inch blade would be appropriate but for fish like small trout, a 7.5 inch blade would do the work. For larger fish, 9 inch blade would be suitable. But if you want a specific answer then the all-rounder is 7.5 inch blade by which you can fillet small as well as large fish without the struggle. 

What is the difference between a fillet knife and a boning knife?

Fillet knife and boning knife have different characteristics and approaches. Fillet knife is specifically used for removing skin and bones from meat especially fish while boning knife is used for removing bones from meat not specifically fish. Fillet knife is more flexible, thinner and ideal for precise cutting while boning knife is thicker than fillet knife and usually straight. A boning knife is sturdier than fillet knife as it is used for tougher meats like beef, pork, chicken or ham.

Final Verdict

Keeping in mind the different characteristics of each of the fillet knives mentioned above it is no less than finding a needle in a haystack to choose the best. But considering factors like versatility, ease of use, flexibility, user rating, grip, cut, smoothness, craftsmanship, protection, sheath, design, sturdiness, non-stick quality the clear winner comes out to be Rapala Fish N Fillet knife. And to complete your knife assortment you also need one of the best Japanese kitchen knives.
