How to sharpen a filleting knife

Due to their odd shape and flexible blade, filleting knives can be difficult to sharpen. The three major ways for sharpening a filleting knife are the same as for sharpening any other kitchen knife:

Sharpener for the tabletop


Wheel for grinding

However, due to the more sensitive nature of many filleting knives, both tabletop sharpeners and grinding wheels will likely to remove a significant amount of the material that makes up the blades, thereby lowering the knife’s lifespan.

Sharpening your KOI Artisan filleting knife using a whet stone is advised. This gives you more control over your sharpening and prevents you from losing too much blade material. Sharpening and honing can both be done with some steels. However, attaining the level of sharpness required for filleting a fish might be challenging at times.
