Rapala Lithium Ion Cordless Fillet Knife
If you don't need the whole set, Rapala also makes a simpler version of their cordless electric knife. This knife comes with a lithium ion battery that provides 80 minutes of continuous use and takes only 2 hours to fully charge. The motor is designed to keep running at full speed even as the battery power is waning, so the knife won't slow down as it runs out of power. The blade of this knife is also very sharp and modeled after the classic fillet knife, which makes it ideal for filleting fish right as they're caught. Of coarse, you don't have to use this knife on a boat. It works just as well in the kitchen, whether you're filleting a fish or carving up a roast chicken.
