Filleting is a key part of preparing fish, whether you cook at home or in a restaurant. It means separating the flesh of the fish from the bones and skin. People have filleted fish with ordinary knives for centuries, but an electric fillet knife makes the job faster and less tiring, especially when you have a cooler full of fish to clean.

Below are the best electric fillet knives you can buy right now, along with the features that set them apart. No knife is perfect, so we also point out the weaknesses you should know about before you buy. The list includes corded knives for the kitchen or fish-cleaning station, cordless knives for the boat or dock, and a few budget electric carving knives that also handle smaller fish.

Updated September 2026: product availability, specs and prices re-checked.

1. KastKing Speed Demon 110V Electric Fillet Knife

The American Angler PRO that topped the original list was sold out in every version on American Angler’s own store in September 2026. A current corded knife in the same class is the KastKing Speed Demon 110V.

KastKing rates its AC motor at 15,500 RPM. The 8-foot power cord means you won’t need an extension cord at most cleaning tables. It comes with two sets of blades: 7-inch Finesse blades for panfish and walleye, and 9-inch Talon blades for larger fish. Both are 420 stainless steel with a titanium coating to resist corrosion. The handle has a non-slip soft coating, and the knife is ETL certified.

The Angler Pack includes a zippered, water-resistant carrying case. It was about $50 (September 2026) on KastKing’s site, which makes it one of the best values here.

Pros of KastKing Speed Demon 110V

• Two blade lengths included
• Long 8-foot cord
• Titanium-coated blades resist corrosion
• Carrying case included

Cons of KastKing Speed Demon 110V

• Needs a wall outlet
• The sharp blades demand careful handling

2. Rapala Heavy-Duty Electric Fillet Knife

As the name says, the Rapala Heavy-Duty Electric Fillet Knife (model HDEFAC) is built for big jobs. Rapala says it has twice the blade speed and three times the power of standard electric fillet knives. Its airflow design is meant to reduce vibration and keep the motor running efficiently during long sessions.

It runs on 110 volts and has an 8-foot cord. The original version of this article said 8 inches, which was a mistake. It uses a 7.5-inch reciprocating blade, and the blade is dishwasher safe. The handle is shaped to reduce hand fatigue, and Rapala backs it with a one-year warranty.

It is no longer a budget pick. It sold for about $91 (September 2026) on Rapala’s site.

Pros of Rapala Heavy-Duty

• Powerful motor for large fish
• Dishwasher-safe blade
• Long 8-foot cord

Cons of Rapala Heavy-Duty

• Comes with a single blade, which limits versatility
• Pricier than it used to be

3. Hamilton Beach Electric Knife Set (74277G)

Hamilton Beach’s electric knife set is a kitchen carving knife first, not a dedicated fillet knife. Still, it handles smaller fish well and doubles as a tool for roasts, turkey and bread. It is the most versatile option here if you only want one electric knife in the house.

It has a 120-watt motor, a cool-touch ergonomic handle and a 5-foot cord. The set includes two 8-inch serrated stainless steel blades, a 6-inch carving fork to steady food while you cut, and a compact storage case. Hamilton Beach covers it with a one-year limited warranty. It was about $30 (September 2026) on Hamilton Beach’s site.

Pros of Hamilton Beach Electric Knife Set

• Works for fish, meat and bread
• Storage case included
• Carving fork included
• Low price

Cons of Hamilton Beach Electric Knife Set

• Serrated carving blades are not as flexible as true fillet blades
• Shorter cord than the fishing-specific knives

4. Berkley 110 Volt Electric Fillet Knife

The Mister Twister electric knife from the original list could not be verified as still on sale in September 2026. Its maker’s site blocked our checks, and we found no current retailer listing. For a simple, affordable corded fillet knife from a fishing brand, the Berkley 110 Volt Electric Fillet Knife (model BCEFK110V) fills the same slot.

It has an 8-inch stainless steel blade that resists corrosion and plugs into a standard 110-volt outlet. Side release buttons keep the blade from coming loose by accident, and a carrying case is included. It was about $60 (September 2026) on Berkley’s site.

Pros of Berkley 110 Volt

• Corrosion-resistant stainless blade
• Carrying case included
• Side release buttons for safer blade changes

Cons of Berkley 110 Volt

• Only one blade length

5. Proctor Silex Electric Knife (74312G)

The Cuisinart CEK-40 from the original list could not be verified as still on sale, since Cuisinart’s site blocked our checks and we found no current retailer listing. A very cheap alternative for occasional use is the Proctor Silex Electric Knife, from the same company that owns Hamilton Beach.

It has a 120-watt motor, reciprocating serrated stainless steel blades with about 7.4 inches of cutting edge, a hand-contoured grip and a 5-foot cord. It weighs about 1.3 pounds. The blades should be washed by hand. Like the Hamilton Beach set, it is really a carving knife, so it suits small fish better than big ones.

It was about $25 (September 2026) at Target, the cheapest knife on this list.

Pros of Proctor Silex Electric Knife

• Very low price
• Lightweight
• Also carves meat and slices bread

Cons of Proctor Silex Electric Knife

• No storage case
• Not designed for filleting large fish
• Hand wash only

6. BLACK+DECKER ComfortGrip Electric Knife (EK500B)

The Black & Decker EK700 from the original list no longer appears on the brand’s site. The current model is the BLACK+DECKER ComfortGrip Electric Knife (EK500B).

The original article described the EK700 as cordless. That was wrong, and the EK500B is also a corded knife. Black+Decker lists a 9-inch serrated stainless steel blade that doesn’t need sharpening, though one major retailer lists 7 inches, so check the blade length before you buy. A safety lock button stops the knife from turning on while it’s plugged in, and a quick-release button pops the blades out for cleaning. The blades are dishwasher safe.

It was about $22 (September 2026) on Black+Decker’s site.

Pros of BLACK+DECKER ComfortGrip

• Safety lock button
• Dishwasher-safe blades
• Low price

Cons of BLACK+DECKER ComfortGrip

• A kitchen carving knife, not a dedicated fillet knife
• Conflicting blade length listings

7. KastKing Speed Demon Pro Lithium-Ion Electric Fillet Knife

The Rapala Lithium Ion cordless fillet knife from the original list was only offered as a combo kit on Rapala’s site in September 2026, and it was out of stock at about $211. For a cordless knife you can actually buy, the KastKing Speed Demon Pro is a strong alternative.

It runs on a 12.6-volt lithium-ion battery. KastKing rates it at up to 1 hour and 40 minutes of continuous run time per charge. A battery indicator shows the remaining charge in 25 percent steps, so you won’t be caught out halfway through a limit of fish. It comes with 7-inch Finesse and 9-inch Talon flex blades with a titanium coating, plus a molded EVA carrying case.

Two kits were offered in September 2026: about $100 with two blades and one battery, or about $130 with four blades and two batteries, on KastKing’s site.

Pros of KastKing Speed Demon Pro

• No cord, so it works on the boat or dock
• Long rated battery life
• Battery level indicator
• Carrying case included

Cons of KastKing Speed Demon Pro

• Costs more than corded knives
• Batteries will eventually need replacing

8. Berkley Deluxe Electric Fillet Knife

The Berkley knife from the original list, with its 6-inch and 8-inch blades, is still sold as the Berkley Deluxe Electric Fillet Knife. Its big selling point is flexible power. It includes a standard 110-volt plug, a 12-volt vehicle plug and battery clips, so you can run it at home, from your truck or from a boat battery.

Both blades are corrosion-resistant stainless steel, and a carrying case is included. It was about $75 (September 2026) on Berkley’s site.

One caution: the few owner reviews on Berkley’s own site were mostly negative when we checked, with complaints about stripped gears and a motor that slowed down under load. Consider it for the power options, but go in with realistic expectations.

Pros of Berkley Deluxe

• Runs from a wall outlet, a 12-volt plug or a battery
• Two blade lengths for small and large fish
• Carrying case included

Cons of Berkley Deluxe

• Owner reviews report motor and gear problems

What to Look For in an Electric Fillet Knife

• Corded or cordless: Corded knives cost less and never run out of power. Cordless knives are easier to use on a boat, dock or anywhere without an outlet.
• Blade lengths: Shorter blades (6 to 7 inches) suit panfish and trout. Longer blades (8 to 9 inches or more) handle salmon, catfish and saltwater fish.
• Fillet or carving knife: Fishing brands like Rapala, KastKing and Berkley design their blades for filleting. Kitchen carving knives from Hamilton Beach, Proctor Silex and BLACK+DECKER work on small fish but are built mainly for meat and bread.
• Cord length: An 8-foot cord gives you room to work at a cleaning table without an extension cord.
• Case: A storage case protects the blades and keeps them from injuring anyone.

Conclusion

Whether you are a home cook or a professional who prepares fish regularly, an electric fillet knife saves time and effort. For serious anglers, the Rapala Heavy-Duty and the KastKing Speed Demon models are built for the job, and the KastKing Pro frees you from the cord. If you only clean the occasional small fish, a cheap electric carving knife from Hamilton Beach or Proctor Silex will do the job and help with roasts and bread too.
