KastKing Speed Demon Pro Lithium-ion Electric Fillet Knife

I recently had the opportunity to try out the KastKing Lithium-ion Electric Fillet Knife (Speed Demon Pro), and I must say, I'm thoroughly impressed! As an avid angler and outdoorsman, I've used my fair share of fillet knives, but this one stands out from the rest. Pros: Powerful and Efficient: The Speed Demon Pro packs a punch with its high-speed motor and lithium-ion battery, making quick work of even the toughest filleting tasks. Ergonomic Handle: The contoured handle fits comfortably in my hand, reducing fatigue and providing excellent control. Superior Blade: The stainless steel blade is razor-sharp and resistant to corrosion, ensuring smooth cuts and durability. Cordless Convenience: The rechargeable battery provides extended battery life, allowing me to fillet multiple fish without needing to recharge. Carry Case: The included carry case is sturdy and convenient, keeping the knife and accessories organized and within reach. Cons: Battery Life Indicator: A battery life indicator would be a welcome addition, as it's difficult to gauge when the battery is running low. Cleaning: The knife's design can make cleaning a bit tricky, but a soft brush and mild soap help resolve this issue. Overall: The KastKing Lithium-ion Electric Fillet Knife (Speed Demon Pro) is an excellent addition to any angler's or outdoorsman's toolkit. Its impressive performance, comfortable design, and convenient features make it a valuable asset for filleting and preparing fish. While there's room for minor improvements, I highly recommend this product to anyone seeking a reliable and efficient electric fillet knife. Recommendation: If you're in the market for a high-quality electric fillet knife, look no further than the KastKing Speed Demon Pro. Its superior performance, ergonomic design, and affordable price point make it an unbeatable value.

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.

Great electric fillet knife that should be in every fisherman's arsenal. Let's start with the ergonomic case that is super slick and filled with foam shaped to hold the knife body and its blades, battery and charger. The case is super slim which makes it very convenient to carry. I bought the knife version with two blades and they are perfect size to fillet both smaller and larger fishes. I even tested the knife on a roast beef during holidays and it cut extremely easy and precisely. I was impressed as meat is tougher to cut than fish. The knife body feels light even with the battery plugged in. Battery has a convenient charge level indicator at the bottom so you can check when it needs to be recharged. Blades are sharp and easy to change. I recommend adding the blades before adding the battery so you don't risk to accidentally start the knife as you are placing the blades in it. As an avid fisherman I have to say this fillet knife is a must have. Cut my filleting time in half if not less. If you are thinking of getting one go ahead I don't think you will be disappointed. Great job Kast King!

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.

First off, I placed the order close to 10pm Thursday night, and it arrived Monday just after lunch. It’s like half the price of some others I was looking at, but I wanted to try it, because I already know that Kast King gear is well built. (I bought a couple of their tackle bags several years ago, and absolutely no issues.) Having said that, must say at the front of this, that the battery pack that came with the knife did not function right out of the box. I plugged it into the charger overnight, but still no juice. So I contacted the supplier, sent them a video of what was going on, and they mailed out a full replacement the next day. AWESOME!! So continuing the review, the semi-soft-case is sturdy, including heavy duty zippers, and everything is neatly organized and protected in the foam interior. I don’t always keep cases that come with tools, but I’ll definitely be using this one. Picking up the knife handle, initially looks big, because it is, especially when you’ve spent most your life with a classic fillet knife, but its rubberized grip feels good in your hand, contoured and secure, even with wet hands. The motor feels plenty powerful. And the noise isn’t bad at all, pretty much what I was expecting. Both sets of blades were very sharp, and clicking them into the handle was easy, as long as they’re aligned. The 9” blade is plenty big for the fish I catch, typically less than 5lbs, but it’s got good flex, and I don’t doubt it will go through scales and ribs no problem. The 7” finesse blade looks perfect. I bet this thing will fly through perch. I’ll update after I’ve had a chance to put it to the test, but initially, I’m very happy with this knife, and the customer service was absolutely excellent.

Works great! Have been an old school rappels knife guy. So easy to use and less wasting of fillets.

This cordless filet knife is great! It's easy to handle and well balanced. Both sets of blades were very sharp, and as long as they’re lined up correctly, locking them into the handle was easy. I love that the battery has a charge indicator and a charger is included. It comes with a case with nice cut compartments and extra room to customize. Easy to store the knife and take on the next fishing trip!

I filet a lot of fish and the bigger they are the harder it is to cut through the rib cage but with this knife which comes with two different blade withs, one wide and one extra skinny this is no longer a problem, it sliced right through with no problem. The other thing it offers is that it's cordless which makes so simple when outdoors or camping, I only used it twice so far and still waiting to see how durable the battery is and the longevity it has. As far as the value for the money it seems to be very good in my opinion.
