You don't need a "skinner" ... a pair of pliers works just fine. Cut thru the skin all the way around the head, then take the pliers and pull the skin towards the tail. I usually like to start right behind the head & on top of the fish and pull the skin down a ways ... then work around to the belly and keep pulling the skin down a little at a time, working your way around the fish until the skin is about halfway down the fish, then get a good chunk of skin in the pliers and pull it right on off. Then you can cut (fillet) the meat off. It's much easier to pull the skin off first, then do the filleting ... and you waste a whole lot less meat, than by trying to take the skin off a fillet.
