my father fot me a 4.5 " blade folding rapala knife for my birthday, can' t wait to use it. we had a mister twister power knife, but it broke and also it seemed to leave a lot of meat on the fish. i found it to be a little wasteful, especially on smaller fish like crappie. however we did havea christmas party with a 6' sub and the electric knife was great for slicing sections for people b/c it did not crush the bread
