i have used hot water, like boil-n-pop, and grabbed with needle nose pliers. also if broken off too deep to grab i have used a very small drill (like in a needle vice, not a power drill) to drill into the peg. then screw in a small eye screw. use the same hot water method and grab the eye screw with pliers to pull out.
the messiest thing i've done is try and drill out the peg w/a power drill. i didn't start with a small bit and work my way up so it made a bigger hole in the forearm, but some heat shrink on the new peg made it fit right. it could of went worse.
