Bubba Tapered Flex 7.5
The Bubba Tapered Flex is the knife I reach for first about 80 percent of the time. The blade is stiff near the handle for piercing the skin and starting cuts, then flexes more toward the tip for following ribs and pulling off the fillet. The trigger-style non-slip grip is a real grip on wet hands. Important in a boat. Stays sharp through a full morning's worth of fish.
I have filleted everything from trout to tuna with these knives. here are the five blades I would actually keep in my kit.
I grew up fishing the Great Lakes and have cleaned a stupid number of fish over the past 30 years. The fillet knife is the one piece of gear that genuinely separates a clean dinner from a frustrating mess of bones. Here are the five blades I would actually buy or have in my kit right now.

Bubba Tapered Flex 7.5
The Bubba Tapered Flex is the knife I reach for first about 80 percent of the time. The blade is stiff near the handle for piercing the skin and starting cuts, then flexes more toward the tip for following ribs and pulling off the fillet. The trigger-style non-slip grip is a real grip on wet hands. Important in a boat. Stays sharp through a full morning's worth of fish.
Rapala Fish'n Fillet 6
The Rapala 6-inch is the classic panfish blade. Birchwood handle, Swedish stainless steel, full flex along the length. It is small enough to work around the small bones of bluegill, perch, and crappie without overshooting. I have had mine since 2004 and it just needs a touch-up on the steel before each outing.
Dexter-Russell SG138N
When I am cleaning a batch of walleye or smallmouth, the Dexter SG138N comes out. American-made stainless, an 8-inch semi-flex blade, and a Sani-Safe handle that you can throw in a dishwasher. This is the knife you see in actual fish-cleaning houses on the lakes. Pro-grade for less than 30 dollars.
Wusthof Classic Fillet 7
For kitchen filleting (skinning a salmon side, breaking down a whole snapper), the Wusthof Classic 7-inch is the right tool. Forged German steel, full tang, comfortable handle. It is overkill in the field but on a cutting board with a clean fish, the precision is real. Worth keeping one premium knife specifically for indoor work.
Bubba Li-Ion Electric
For volume days. cleaning a limit of walleye for the freezer or processing a cooler full of crappie. the Bubba electric is a back-saver. Reciprocating dual blades cut through skin and bones in seconds. Battery lasts about 80 to 100 fish per charge. Not a replacement for a real fillet knife, but a huge accelerator alongside one.
FAQs
Match the blade to the fish. 6 inches for panfish and trout, 7.5 to 8 inches for walleye and bass, 9 inches for salmon and pike, 12 inches for tuna and larger saltwater fish. A 7.5-inch is the best single-knife compromise for freshwater.
For thin-skinned fish (trout, bass, panfish), yes. For thick-skinned and bony fish (catfish, pike, large salmon), a stiffer blade gives you more control. The Bubba Tapered Flex is the closest thing to a do-everything blade.
