The best fillet knife blade sizes range from 4 inches to 9 inches, with the smaller sizes used for smaller fish and larger sizes used for larger catches. In general, the middle-of-the-road knife size or having two sizes for catching and cooking different fish are the best options. The blade must have a protective edge property and be constructed from high-quality, durable stainless steel.

Also, knives with a stain-free coating will keep the tool in tip-top condition and further repel bacteria from building up around the blade.

Precautions of Using Fillet Knives

Even when using the best fillet knife, there are many precautions you must take. Ensure the kitchen knife is regularly sharpened and maintained before use.

When using the best fillet knife, use a flat surface or cutting board and place a damp cloth under to prevent slippage. Since fillet knives are inherently sharp, always keep it in a sheath with the point down and cutting edge away from you.

When not in use, the knife should be stored securely with the blade down and kept out of reach of children. Never use a fillet knife to cut anything other than its intended purpose: fish or game. This can easily lead to mishaps and injuries. While many of the best fillet knife products are dishwasher safe, it is always best to hand wash knives after use and never drop them into dishwater in the sink. Remember, if the knife is sharp enough to cut through animal hide and flesh, then it can easily slice through human flesh.
