A scratch awl is the perfect tool for driving small holes in your leather to aid in sewing. Scratch awls are also useful in scrimshaw, quilting, and gently poking someone when they aren't paying attention. Be careful, they are sharp!
This awl is perfect for traveling as well as re-enactments. It's small enough to pack and not take up space. It does the job because i already tried it. The price you can't beat it.
