9″ + 7″ dual blades · 12V removable battery · Two-step safety lock
A 12V cordless fillet knife built around three deliberate decisions: two blades for two different jobs, a battery that comes out of the handle with a charge gauge you can actually read, and a safety lock that has to be clicked before the trigger does anything.
Not a feature list — three things that were designed a particular way, and the reason why.
Two blades for two different jobs, both in the box. The 9-inch stiff blade drives straight through thick cuts. The 7-inch flexible blade bends along the bone line on smaller fish. You're not choosing at checkout — you get both.
The 12V 2000 mAh pack slides out of the handle, so it charges and stores separately from the knife. A three-bar LED gauge on the body of the knife shows the charge level before you start, instead of finding out halfway through the cooler.
A red lock button sits apart from the trigger. The blade won't move until the lock is deliberately clicked and the trigger is pulled. The blade release sits in its own position too — not stacked under the finger you're already using.
Both ship in the box because they do different work. Here's how to pick without guessing.
Straight answer on sharpening: serrated blades in this category can't be honed back like a straight edge — that's true of every brand, ours included. They wear rather than dull evenly. What we did about it is put both blades in the box from day one instead of selling the second one as an upgrade, and make the blade release a single button so switching between them takes seconds.
The grip is fully wrapped in non-slip rubber — it's the part you'll be holding with wet hands for twenty minutes straight.
The manual lists four food groups this knife is made for. These are those four — nothing invented.
Not for: bone-in meat, frozen or partly thawed food, very hard produce like raw pumpkin, or submerging the handle in water. All four limits come straight from the manual, not from us being cautious.
Straight from the manual — not a simplified version of it.

These are the questions that come up most about cordless fillet knives — including the awkward ones. Here's where we stand on each.
Serrated blades wear rather than dull evenly, and they can't be honed back like a straight edge. That's the reason both blades are in the box rather than sold as an upgrade: you start with the stiff edge and the flex edge already covered, and switching between them is a one-button job.
Small panfish are where electric knives are weakest, full stop — bigger teeth chew more than they cut. The 7-inch blade is the flexible one, so it tracks the curve of the bone rather than driving straight through it. That helps. It still won't beat a sharp manual fillet knife on a bucket of bluegill, and we're not going to claim it does.
On a lot of cordless knives the trigger and the blade release end up stacked, so your thumb ejects the blade while you're working. Ours are separated: the trigger sits under the index finger, the release is up by the thumb in its own position, and the red safety lock has to be clicked before the trigger does anything at all.
One more we won't dress up: a skilled hand with a sharp manual fillet knife still gets more meat off a fish than any electric knife, including this one. What an electric buys you is time on a big batch — not a better fillet.
Every number below is printed in the user manual. If a number isn't here, it isn't because we're hiding it — it isn't in the manual either.
Runtime: the manual gives the pack capacity (2000 mAh) and the charge time (5–6 hours), but no runtime figure — so we don't quote one. We'd rather leave a gap here than publish a number we haven't measured.
Water: not waterproof, and there's no IP rating. The manual says plainly not to rinse or immerse the handle. Wipe it with a damp cloth; the blades wash normally.
The hard-shell case holds the handle, both blades, the battery and the charger in cut foam. That's also what makes it a workable gift for someone who fishes — it doesn't need a box, and it doesn't sit in a drawer.
You get both — they ship together. Reach for the 9″ stiff blade on thick cuts and anything you're slicing straight through, and the 7″ flex when you need to follow the curve of a bone on a smaller fish.
We don't publish a runtime figure, because the manual doesn't give one and we haven't measured it ourselves under conditions we'd be willing to stand behind. What we can tell you: it's a 12V 2000 mAh pack, a full charge takes 5–6 hours, and the three-bar LED gauge on the knife body tells you where you stand before you start.
No — we sell the complete kit only, and we don't stock blades or battery packs as separate parts. Both blades and the battery are in the box. If something arrives faulty or fails on you, that's a returns and defect matter rather than a spare-parts one: email support@wellmallpro.com and we'll sort it.
No, and be sceptical of anyone in this category who says otherwise. Serrated electric blades wear out rather than dull evenly, and they can't be honed back like a straight edge. Shipping both blades in the box is the answer we have to that.
No. There's no IP rating and the manual explicitly says not to rinse or immerse the handle — water inside the housing will kill it. Wipe the handle with a damp cloth and dry it; the blades come off and wash normally.
No to both. Thaw fish first, and keep it off bone — the manual lists both as things that will damage the blades. Very hard raw produce like pumpkin is out too.
Up to five minutes at a stretch, then let the motor cool. That's a manufacturer limit to prevent overheating, not a suggestion. On a big batch it means working in rounds.
It ships from our U.S. warehouse in 3–5 business days, free on orders over $36.99. You have 90 days to return it, and we replace defects free.
Two blades, a battery you can read, and a lock that has to be clicked first. In its own case.
