i'd have to agree with some of these guys, i am 39 yrs old and up til a year ago, i had used an old fillet knife since i was 16 . but we had a lot of fish to fillet one day and my friend pulled his electric one out and laughed at my old knife. after watching him fillet more than 3 to my 1, i got one and learned how to use it. now i love it and wouldnt go back
