1 All-round filleting from the dock to the boat deck
The best all-round fillet knife for most anglers: a thin, flexible 7-inch blade and a non-slip handle built for wet hands, at a mid-range price.
Pros Grip stays secure with wet, slimy hands Thin, tapered blade follows the backbone well Buyers frequently praise how well it holds an edge Full tang with a finger guard, lanyard hole and sheath Cons Costs more than basic fillet knives 7-inch blade is short for big salmon or tuna, and long for small bass Sheath is designed for belt carry Only a 1-year limited warranty 2 Salmon, striper and bigger saltwater fish on a budget
The best budget 9-inch fillet knife: a long, flexible, coated blade for salmon and saltwater fish, a grippy handle and a draining sheath for about $25.
Salmon Striper Redfish Snapper Pros Long, flexible 9-inch blade for salmon and big fish, under $30 Corrosion-resistant coated G4116 steel for fresh or saltwater Grip stays put when wet; buyers praise the comfort Most-rated manual knife we cover: 4.7 out of 5 from 3,700+ ratings Cons Too long and flexible for small panfish No sharpener in the box (knife and sheath only) Still rinse and dry it after saltwater, like any knife 3 Big saltwater fish, king salmon, game and carving
The best stiff fillet knife for big fish: a thick 9-inch blade with almost no flex for tuna, king salmon and game, plus BUBBA's non-slip grip.
Tuna King salmon Halibut Wahoo Pros Stiff, 2 mm blade powers through big fish and heavy meat with control Beveled, non-stick blade slices thin, clean cuts BUBBA's grippy handle stays secure when wet or greasy Rated 4.8 out of 5 on Amazon Cons Very large (15 inches overall); too much knife for small fish Too stiff for skinning delicate fillets Sold by a third-party seller with slow delivery when we checked Only a 1-year limited warranty 4 Cleaning big catches fast, fresh or salt
The best electric fillet knife for most people: cordless, with four blades from 7 to 12 inches, so one kit covers panfish limits up to large saltwater fish.
Crappie limits Salmon Snapper Mahi Pros Cordless, so it works on the boat, dock or cleaning station Four blades: 7" and 9" flex plus 9" and 12" stiff Two batteries included, each with a charge indicator Buyers rate it 4.7 out of 5 across more than 6,000 ratings Cons Expensive Big, heavy handle (about 1.1 lb); some buyers with smaller hands find it awkward On Amazon it's sold by third-party sellers; some buyers report warranty pushback for non-authorized sellers Only a 1-year limited warranty 5 Large freshwater and inshore saltwater fish on a budget
The best value fillet knife: a long 9-inch blade, grippy handle, sheath and lifetime warranty for under $20, as long as you keep it sharp and dry.
Salmon Striper Snapper Lake trout Pros 9-inch blade handles salmon and other big fish for under $20 Handle stays grippy when wet or slimy Light (3.6 oz) with a sturdy ABS sheath and belt loop Kershaw limited lifetime warranty Cons Soft 420J2 steel needs sharpening often; some buyers say it doesn't hold an edge Some buyers report small rust spots on the edge, so dry it after every use Long blade is less nimble on small panfish 6 Salmon, steelhead and long fillets at the cleaning table
The best fillet knife for salmon and steelhead: a long, narrow, flexible 9-inch blade from a US commercial cutlery maker, but you'll need to buy a sheath separately.
Salmon Steelhead Lake trout Halibut Pros Long, narrow, flexible blade made for big fillets Commercial-grade, NSF-certified handle Made in the USA Takes a keen edge and is easy to resharpen Cons No sheath in the box (the Dexter WS-1 adds about $14) Some buyers report rust spots, so hand wash and dry it Large finger guard can catch on the cutting board 9 inches is too long for small fish; some buyers find the flex stiffer than expected 7 Trout, perch and other small-to-medium fish
A light, sharp Swedish fillet knife with better steel than most budget knives, for small and medium fish.
Pros Sandvik 12C27 holds an edge well and resists rust Soft friction grip and finger guard; handle doesn't absorb odors Very light: 3.5 oz including the sheath Rated 4.8 out of 5 by Amazon buyers Cons 6.1-inch blade is short for salmon and big saltwater fish Costs more than the Kershaw, KastKing 9-inch and Fish & Bone budget picks 8 Carrying a full-size fillet knife in a tackle bag, backpack or kayak
The best folding fillet knife for most anglers: a flexible 6.5-inch blade that folds to 7.5 inches for a tackle bag or backpack, for under $30.
Pros Folds from 13.5 to 7.5 inches, so it fits in a tackle box or pack Feels as solid as a fixed blade when open, according to many buyers Flexible 6.5-inch G4116 blade with a non-stick, corrosion-resistant finish Rated 4.7 out of 5 from more than 2,300 Amazon ratings Cons A folding hinge traps slime, so it needs more careful cleaning than a fixed blade A few buyers received one that needed sharpening out of the box 6.5-inch blade is short for big salmon and saltwater fish 9 Cutting bait and filleting small panfish
A cheap, compact bait-and-fillet knife: a stiff 5-inch blade with a serrated spine for bait, and small enough for bluegill and crappie.
Bluegill Crappie Perch Cut bait Pros Serrated spine cuts frozen bait Compact 5-inch blade is precise on small fish Sheath locks the handle in and drains water Under $20 with a sheath and KastKing's original-owner warranty Cons Stiff blade, not a true flexible fillet knife Too short for anything above medium-sized fish How we chose the best fillet knives for saltwater Corrosion-resistant steel or coating Synthetic, non-slip handle (no bare wood) Sheath that drains and won't rot Blade long enough for bigger saltwater fish Salt attacks steel fast. Even a stainless steel fillet knife needs a fresh-water rinse and a dry before storage.
Avoid leather sheaths for saltwater: they hold moisture against the blade.
