5 Best Knives for Fileting Fish & Reviews

More than possibly any other ingredient, fish requires special handling.  Fish needs to be kept super cold to prevent deterioration and should be cut with the sharpest knife possible to preserve the cell structure and offer the best end result . In this article we will focus primarily on sujihiki, which are the Japanese version of a slicing knife and talk about why they make the perfect filet knife.

How to Select the Best Filet Knife

The main considerations when choosing a knife, filet or any other type, is blade material, stainless or carbon, steel type, blade angle, weight, handle material and length and price. All of these considerations are personal preference, but a good way to narrow down your options.  Our guide to choosing a chef’s knife can help walk you through the pros and cons of the choices available.
