Best Game/Utility Shears?

I cut up a lot of squirrels and rats to feed to my hawk. Shears are much nicer for this than a knife. I've been using a $2 pair of utility shears from harbor freight, but they're wearing out and I'd like something better.

Does anybody here have an experience with game shears? I don't care if they're kitchen shears or even metal shears, just as long as they're reasonably lightweight and will cut through everything from squirrel skin to rabbit bones.
