For a very long time. The first powered knife was a mister twister that wore out. I have used Rapala electric and battery powered fillet knives. The electric setup is great if that power source is desired. However the lithium battery powered fillet knife set with extra blades and a second battery is my favorite. It and cleaning gear live in my truck.

Both of these system are excellent for cleaning walleye and perch. Get a good electric or battery set and learn to use it. In the winter take the batteries inside where warm.

Get a Rapala glove for your fish holding hand. You still need to be careful.

Hope this will help and you like the setup.
