I use a townsend fish skinner for removing the rib cage. It works great and very quick. You just need to make sure you grab the big end of the rib cage and two twists done deal.
Cheers Don.
EDIT: Bill thanks for that video above. I didn't know about the zipper technique to remove that Y bone. Wonder if that would work for grass pike and musky?
