If fishing is part of your typical outdoor weekend—or you do a lot of campsite cooking—it’s a good idea to add on of our picks for best fillet knife to your cooking gear. But a quick internet search will reveal that—no surprise—there are a lot of options. Here at Camperville, we’ve done the legwork for you and rounded up the best fillet knives we could find.

But first, here are some things to consider when choosing a fillet knife.


How will the knife be used? Will it be used primarily for fish or game? Or will it be multipurpose? The knife’s main job plays into which model is the best choice for you.


Most fillet knives are made from stainless steel, carbon steel, or titanium. In most cases, a high-carbon steel blade will do the job.


Fillet knives are usually available in blades ranging from 6 to 9 inches. The size you choose depends on how you plan to use it. A 6-inch blade is fine for most freshwater panfish but larger fish may require a larger (9 inches or more) blade.


No-slip handles are pretty much standard these days, but it’s still worth thinking about the type of grip you’re looking for.
