I finally tried an electric fillet knife for the first time last weekend. We had well over 100 fish to clean & I thought it would be a great opportunity to try out the electric when there was enough to really see if I was going to like it or not. I do. I'd say that yes, I may leave a little more meat on the carcass than I do if I fillet them with a regular knife, but not much. And it is sooo much faster & better at getting the skin off. Only used it once but for now, I'm sold.

I got the Rapala AC/DC model at Walmart for $39.
