Best Fish Fillet Knife
Are you someone who loves seafood and is dying to cook up a gorgeous piece of fish? Whether you’re a beginner or advanced chef, everyone needs the right equipment to prep their favorite fish. When preparing a fish to cook, you need to carefully and skillfully cut the fish into thin slices. This process is called filleting a fish. For practical purposes, you need to use a fillet knife to remove bones from fish and cut into small pieces. A regular knife can do the job, but it’ll be much more difficult and cumbersome. A fillet knife is much thinner and flexible, allowing you to maneuver inside the fish to remove bones with ease.

It’s got a nice grip especially a little point when you can put your thumb and pointer finger under. This prevents your knife accidentally cutting your fingers.
For fishermen out there, this is an excellent knife to bring out to after you’ve caught your fish and cut out all the excess fat and bones. It’s also fantastic in the kitchen as well. If you’ve caught an extra bony type of fish, we recommend you buy the serrated versions as well to really cut through the fish with ease.

When it comes to versatility, this knife will take care of your catches easily. We found the rubber handle is quite sturdy, and the knife length makes the cutting efficiency. We like how the sheath is very breathable and has open rectangle holes to let out water and air into the knife. You want to make sure the knife is clean from water and fish after you’re done filleting.
One thing we’ve noticed is that the fish is rigid and when you bend it too much, it and wear down the blade. It does have a beautiful curvature to make it easy to maneuver when you’re inside a fish. I’ve cut through countless catfish and bluegill with this knife, and it still holds a sharp edge with no wear and tear. For under $30, you’re getting functional fillet knife that will last you a very long time, in my opinion. I love the little belt clips it has so I can carry it around to use after I’m done fishing.
