Choosing a Fillet Knife

• Blade length should match fish size. 6 inches for panfish, 7 to 9 for bass and walleye, 9+ for saltwater species.
• Flexibility allows the blade to follow the backbone. Stiffer blades are better for larger, thicker fish.
• Non-slip handles prevent accidents. Fish cleaning is inherently slippery.
• Keep the blade sharp. A dull fillet knife tears flesh instead of cutting it cleanly.
