I carry a Swedish Mora from any camping store or Peavy Mart for a bush knife. $8-$10 . It gets the bush chopping, bean can opening, split the brisket with a knife and rock type of jobs. If you lose it, who cares.
Then you can spend whatever you want on a skinning knife. It's guaranteed to still be sharp when you need it the most, and you're not tempted to do terrible things to it.
Pick a budget, and go shopping for your skinner. There are so many different handles and sizes out there now, it's best to find the one that fits your hand the best. There's nothing wrong with the $50 rubber handled Oldtimers from Wally world. They perform very well when wet and slimy with animal goo. For that matter, you could carry two Mora's for a grand total of $20.
