WORKPRO 12V Cordless Electric Fillet Knife, 8" & 10" Sharp Blades

Processing a fresh catch on the dock or in the kitchen gets significantly faster with a dedicated electric fish knife. The WORKPRO 12V Cordless Electric Fillet Knife delivers portable cutting power away from wall outlets, using interchangeable reciprocating blades and swappable battery packs to handle everything from delicate panfish to dense saltwater game.

Runtime management is straightforward thanks to the dual-battery configuration. Each 12V pack holds three 3.7V 18650-2000mAh lithium-ion cells, offering up to one hour of continuous cutting per charge. Because the included fast charger completely recharges a pack in one hour, you can keep one battery in use while the other recharges, eliminating long work stoppages during heavy catch days.

Cutting versatility comes from two distinct carbon stainless steel blades included in the box. The 8-inch flexible blade bends easily around smaller bones for species like flounder, snapper, or perch, while the 10-inch stiff blade provides the rigidity needed for larger fish like tuna, halibut, salmon, and swordfish. Both blades feature sharp reciprocating edges designed to slide cleanly through meat and tough skin.

Handling remains manageable thanks to a bare tool weight of just 1 pound (excluding the blade and battery). A rubber-coated handle provides a secure, non-slip grip when hands are wet or slimy, while a mechanical lock keeps the battery securely seated in the handle so it will not dislodge under cutting pressure. When the job is done, every component fits inside a heavy-duty carrying case for tidy storage.

Every cordless tool introduces natural design trade-offs. While the bare handle weighs only 1 pound, snapping on a lithium-ion pack and a 10-inch steel blade increases the total working weight in your hand. In addition, users must proactively cycle and recharge both packs during marathon cleaning days to prevent downtime, rather than simply plugging into an infinite wall outlet.

Verdict: This cordless electric fillet knife is an excellent pick for anglers who clean their catch at the dock, campsite, or cleaning table without accessible electrical outlets. If you process fish where power is unavailable and value having two blade styles in a self-contained kit, it is well worth adding to your gear bag.

• Tool Weight: 1 lb (excluding blades and battery)
• System Voltage: 12V
• Battery Capacity: 2.0Ah (two packs included, three 3.7V 18650-2000mAh cells each)
• Battery Charge Time: 1 hour with included 12V fast charger
• Battery Runtime: Up to 1 hour per battery pack
• Blade Types: 8-inch flex blade and 10-inch stiff blade
• Blade Material: Carbon stainless steel

A great fit if you:

• Clean fish outdoors at docks, boat ramps, or campsites where electrical outlets are not readily available.
• Target a variety of species and need both an 8-inch flexible blade and a 10-inch stiff blade in one kit.
• Process moderate batches of fish and appreciate having a backup battery charging while you work.
• Prefer a lightweight rubberized handle that helps maintain a secure grip during messy cleaning jobs.

Consider something else if you:

• Prefer a traditional non-motorized manual fillet knife that requires no batteries, charging, or blade assembly.
• Process massive commercial quantities continuously and prefer an unlimited-runtime corded electric knife.

Confirm on the listing:

• Check whether replacement blades or additional battery packs are sold individually if you plan on long-term expansion.
• Verify the exact interior dimensions and weight of the storage case to ensure it fits inside your existing tackle locker or boat hatch.
• Check the manufacturer instructions for recommended cleaning and lubrication procedures for the reciprocating carbon stainless steel blades.

How to compare your options: When choosing a fish fillet knife, focus on power source, cutting flexibility, and runtimes. A cordless model like this WORKPRO kit trades the infinite runtime of corded tools for true dockside portability, which is made practical by its matched 1-hour charge and 1-hour discharge cycle across two batteries. Having both 8-inch flex and 10-inch stiff blades also ensures you are not stuck using a single blade geometry across very different fish sizes.

To ensure steady power throughout your fish cleaning sessions, place the spare 2.0Ah battery pack on the 12V fast charger as soon as you begin working with the first battery. By rotating packs as one depletes, you can maintain continuous cutting without waiting around for cells to charge.

Match the blade to the fish species you are processing. Choose the 8-inch flex blade for following delicate bone structures on species like snapper, flounder, or ocean perch, and swap to the 10-inch stiff blade when working through larger carcasses like halibut, tuna, or salmon.

Always verify that the safety lock is engaged so the battery remains firmly seated inside the handle during operation. After use, ensure all blades and components are clean and completely dry before packing them away inside the heavy-duty carrying case, which helps protect the carbon stainless steel from moisture and prolongs service life.

How long does each battery last on a charge?
Each 2.0Ah lithium-ion battery pack provides up to 1 hour of usage. Since the kit includes two batteries and the fast charger finishes a full charge in 1 hour, you can rotate between them for extended jobs.

What blades come included in the kit?
You get two interchangeable reciprocating blades: an 8-inch flexible blade designed for agile cuts and a 10-inch stiff blade suited for larger fish species.

What kind of fish can this knife fillet?
The carbon stainless steel blades are suited for a wide variety of fish, specifically including snapper, cod, flounder, tuna, swordfish, halibut, salmon, and ocean perch.

How heavy is the tool during use?
The bare knife handle weighs only 1 pound, though the total weight in hand will increase slightly once you lock in a blade and a 12V battery pack.

What is included in the package?
The set includes the electric knife handle, an 8-inch flex blade, a 10-inch stiff blade, two 2.0Ah lithium-ion battery packs, a 12V fast charger, and a heavy-duty carrying case.
