Obviously. your Kentucky lake guide doesn't know how to use it!!10inchgill said:my kentucky lake guide service guide used an electric filet knife on our crappie 2 weeks ago. he was done in no time. but of course he should be quick as those crappie were mutilated. those knives leave more meat on the carcasses and skin than should be allowed by law. try one on a turkey, you get turkey sawdust with the slices. sharpen a hi carbon filet knife properly and perform fish surgery like a pro. perfect, full filets are worth the effort! nothing good ever comes from rushing. pun intended!
