Speed Demon Pro

A very handy and functional tool. Cordless for convenience. Includes exactly the two blade sizes I need... one suitable for panfish and one for larger fish. The supplied blades were extremely sharp. As others have mentioned, they are a little fidgety to install, but it's really no big deal. They stay put.The included case is very nice! It's quite slim (think of the form factor as being like a large book -- see photo) and there is room inside for doing some custom work to make slots for additional blades if you desire. The fact that it will reportedly accept blades from other brands is a plus, if accurate. The battery has the capacity to very easily handle as many panfish as I usually clean at once (10-15). The battery has a cool "fuel gauge" to read out the current charge level and a nice A/C-powered battery charger is included.I haven't used it enough to comment on blade edge retention, but I can easily sharpen that type of serrated blade with a small triangular stone, so it's not a concern to me. The build quality looks and feels very good and the ergonomics are excellent.The only drawback --and it's a minor one-- of an electric filet knife is that the handle is much larger in diameter than a normal filet knife and the blade is a little less flexible, so it's necessary to set up your fillet board next to the edge of the counter or table or raise it up on a block so you can get the knife horizontal to your work. I know that some folks like to keep a traditional filet knife handy for taking the skin off the fillets, but I don't find that necessary.I'm happy with this KastKing knife and think it's a good value, like their other products. I've been debating buying an electric fillet knife for years and I'm glad I finally got one.

The Kastking electric fillet knife(Demon-pro) is a must for every fisherman. First the convenience of not having to plug in is huge: I used it to cut the throat of the walleye I caught to bleed them out in my live well. Next I was able to clean the walleye on shore without needing an outlet and having a power cord in the way. Super convenient.The case is super slim which makes it very convenient to carry to the boat. It comes with two blades and they are the perfect size to fillet both smaller and larger fish(Walleye and perch in my case). I will even use it to carve the Turkey on ThanksgivingThe stainless steel blades are razor-sharp and resistant to corrosion, ensuring smooth cuts and durability. Its high-speed motor and lithium-ion battery make quick work of even the toughest filleting tasks. The contoured handle fits comfortably in my hand, reducing fatigue and providing excellent control.Its superior performance, ergonomic design, and affordable price point make it an unbeatable value!

Really like the knife! Love the finger guard! It seems to have plenty of power. Two sizes of blades are a must and they are pretty damn sharp, I appreciate that! The soft case is nice but I would prefer a hard shell case. Love the flexibility of cordless! Construction appears to be pretty solid. Haven't yet used it on a fish but will be testing soon. I will update at that time. Overall pretty awesome product. 4 stars for the preference for a hardshell case.

As with all KastKing products, it is well built and functional. The handle fits the hand well and is big and heavy enough to fillet through any size fish. The rubber coating helps to keep a good grip whiling cleaning wet and slimy fish. With the two blade option, it lets you choose the best blade depending on the fish size. Also with it being cordless, you are not limited to your location for cleaning. The case is well designed and keeps everything organized. The overall thought for the fillet knife is a thumbs up.

This cordless design is a game changer. It's a lot easier and safer to use. And the best thing is that you can take it with you on a fishing trip and clean the catches on the spot. The two battery packs act as an insurance in case one is not fully charged. The carry case is sturdy and compact. Couldn't be happier with the purchase. Highly recommend!

I’ve used several electric fillet knives over the years, but this KastKing Fillet Knife really stands out. The cordless design is incredibly convenient, especially when I’m cleaning fish at the dock or in areas without a nearby outlet. The batteries last longer than expected—I was able to fillet an entire cooler of fish without needing to recharge.The knife is well-balanced and powerful enough to handle everything from panfish to big saltwater species. The blades are sharp and easy to swap out, and the included case keeps everything neatly organized. Great product!
