I finally found a decent electric knife, its rapala's heavy duty model, runs off of 110 and doesn't come with a case or extra blades. It was 49.99 on sale at gander mountain. buzzes through the big fish in no time. i purchased the regular model rapala last year and it had trouble with big fish and would get hot. it got the job done but not like this heavy duty model. I don't work for rapala or gander mountain and do not get commission, I was just really impressed with this knife.
