### ⭐⭐⭐⭐⭐ Review
*by D***B on 13 June 2025*

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.
