The Rocket Tool is an awl with the most perfect taper for chainmaking. Use the pointy end for moving rings out of the way, opening a little space to put another ring through, etc. Some weaves are almost impossible without a pointy stick... and this is much nicer than a toothpick. I have other awls, some with points that are too fat, too sharp, not comfortable to hold (I sound like Goldilocks) but this one is just right. The fan shaped end can be used to remove and replace watch pins or as a blade for opening letters, packages, etc. It's a handy little thing to have around.
