When I get into filet on some trout, (salmanoid) I had such good luck with 2
knives....one was an el cheepo electric that I use to cut thru the coarse work,
then I would swap over to the rapala for the fine detail work like the "Y" bones
on the ribs and any skinning. Catfish and bass and seafood are another animal,
but that dang ole cheepo electric sure makes short work of a big cleaning job.
Edit: That was a Black & Decker electric btw.
