Nine corded and cordless electric fillet knives for cleaning a limit of panfish, walleye or catfish, with a chart of which blade length suits which fish.
An electric fillet knife earns its place on the day you come home with thirty crappie. A manual blade is the better tool for one big walleye, but a bucket of panfish is a lot of small, fiddly cuts, and a reciprocating blade that saws straight through the ribs turns an hour at the cleaning table into a much shorter job. You give up a little meat along the rib cage and you gain your evening back.
The real decision is corded or cordless. A corded knife never runs flat and costs less, so it suits a garage, a cabin or a cleaning station with an outlet. A cordless knife goes to the dock, the boat ramp or the ice, and the good ones ship with a second battery. After that, look at the blades in the box: a 6 to 7.5 inch flex blade for panfish, something longer and stiffer for catfish and pike.
If you only buy one, get the BUBBA Li-Ion. It has the most Amazon ratings on this list by a wide margin and comes with four blades and two batteries. On a budget with an outlet nearby, the Rapala Heavy Duty or the Mister Twister does the job for a fraction of the price. Tom has not tested these knives.

The knife does the cutting. These make the job safer and stop the mess spreading across the dock or the garage.
Corded for an outlet, cordless for anywhere. Make sure the box has a blade that suits your usual fish.
For the hand holding the fish. A slipping reciprocating blade cuts fast. American Angler and Smith's include one.
Something you can hose down. A board with a clamp at the tail end holds slippery panfish still.
Fillets go straight onto ice. Bag them by meal size so you thaw only what you cook.
Cordless: a charged spare. Corded: an outdoor-rated extension cord and a GFCI outlet.
Common starting points for freshwater fish. A blade a little longer than the fillet is wide gives a clean single pass; flex blades follow small frames, stiff blades hold a line on big backbones.
Short and flexible for small fish. Ranked picks: Rapala Heavy Duty (#3) at an outlet, Rapala R12 (#9) with its 6 in blade, or Bubba's 7 in flex blade (#1, #2).
Long enough to take a keeper walleye fillet off in one pass. Ranked picks: Bubba Li-Ion (#1), WORKPRO with its 8 in flex blade (#4) or KastKing Pro Li (#8).
Stiff blades that will not bow on a thick backbone. Ranked picks: Bubba's 12 in stiff blade (#1, #2), American Angler PRO (#6) or WORKPRO's 10 in stiff blade (#4).
A kit that swaps blades for whatever came home in the cooler. Ranked picks: the two Bubba kits (#1, #2) or the American Angler PRO (#6).

Corded knives run as long as you need and weigh less in the hand because there is no battery in the grip. Cordless knives go anywhere, which matters at a lake access with no power or out on the ice. If you clean fish at home every time, a corded knife is the cheaper and simpler buy.
Cordless run times on these listings range from about an hour per battery (WORKPRO) to 80 minutes (Rapala R12) to 1 hour 40 minutes (KastKing Pro Li). A second battery in the box, as with Bubba and WORKPRO, does more for a big cleaning session than any single number. KastKing's battery packs are not sold separately, per its listing.
Short flex blades, 6 to 7.5 inches, follow the small frame of a bluegill or perch. Walleye and bass are easier with 7.5 to 9 inches. Catfish, pike and big carp want a 9 to 12 inch stiff blade that will not bow on the backbone. Kits with four or five blades (Bubba, American Angler) cover all three; a single 7.5 inch blade covers the first two.
Hands get wet and slimy, so look for a rubberized or textured grip and a trigger guard or safety lock. Removable blades are standard. Rapala says its Heavy Duty blades are dishwasher safe; the motor body never goes in water on any of these knives, so wipe it down instead.
A short flex blade and a fast saw through the ribs. The Rapala Heavy Duty or Mister Twister at an outlet, or the Bubba Li-Ion on the dock.
Clean at the ramp before the fish go in the cooler. WORKPRO is the cheapest cordless here with two batteries; Bubba Li-Ion is the one with the deepest buyer record.
You want a long stiff blade and torque. Bubba's kit includes a 12 in stiff blade, and the American Angler PRO ships with 8 and 10 in heavy-duty blades.
The usual method for crappie and bluegill. Let the motor do the work and keep steady, light pressure.
Lay the fish on its side and cut down behind the gill plate until the blade touches the backbone. Do not cut through it.
Angle the blade toward the tail and saw along the backbone through the ribs, stopping just before the tail so the fillet stays attached.
Fold the fillet back over the tail, set the blade between skin and meat, and run it forward while holding the tail.
Cut out the thin strip of rib bones with a short curved cut. A manual knife is easier for this step on small fish.
Rinse the fillet, put it on ice, and do the other side. Wipe the handle dry between batches.

For volume, yes. An electric knife cuts through the rib cage in one pass, which makes a pile of crappie or perch much faster to clean. For one or two bigger fish, a sharp manual knife is quieter, wastes less meat and is easier to keep clean. Many anglers own both and grab the electric when the bucket is full.
Corded if you always clean fish near an outlet, because it never runs out and costs less. Cordless if you clean at the dock, in the boat or on the ice. If you go cordless, a model that ships with two batteries, like the Bubba Li-Ion or WORKPRO, saves you from waiting on a charger halfway through.
A 6 to 7.5 inch flexible blade is the usual choice for bluegill, crappie and perch. It is short enough to control on a small fish and flexes along the backbone. Rapala's R12 includes a 6 inch blade, and Bubba's kits include a 7 inch flex blade.
Any knife with a 7.5 to 9 inch blade handles walleye well. On this list the Bubba Li-Ion includes 7 and 9 inch flex blades and is our top pick; the Rapala Heavy Duty, with a 7.5 inch blade, is the budget choice if you clean at home.
A little more than a careful manual cut, mostly along the ribs. The common method is to cut down to the backbone, saw along it through the ribs, then skin the fillet and trim the rib section off with a second short cut. On small panfish the time saved usually outweighs the few grams lost.
The serrated reciprocating blades on these knives are hard to sharpen at home, so most anglers replace them when they dull. Check that replacement blades are sold for the model you buy. American Angler's listing names compatible replacement blades, and Bubba says its blades fit both its corded and cordless knives.
Keep the motor body out of water and plug into a GFCI-protected outdoor outlet, which cuts the power if current leaks to ground. Unplug or remove the battery before changing blades, and use a cut-resistant glove on the hand holding the fish. Two kits here, American Angler and Smith's, include a glove.
