Here's a versatile tool that every lure fishermen should have on his workbench. I use a high-quality countersink to de-burr the end of my leader tubes so there are no sharp edges to bite the leader. For simple de-burring, you can use the countersink as a hand tool or spin it with a portable electric drill. When used with a drill, the bit also works great for modifying the faces of your lures to create different actions. The lures in the accompanying photo all came out of the same round-nosed mold.
