I use a 8" Dexter or Forschner Breaking knife for my filet jobs
On fish with heavy rib bones,I cut over the top of the bones and not through them.I use a pair of game shears to cut off the ribs and the breast,those are some tasty parts I really enjoy.

As Bob Hagel would say"You should not use a rifle that will kill an animal when everything goes right; you should use one that will do the job when everything goes wrong."Good words of wisdom...............
