The Speedy Stitcher is a sewing awl that I have used to fix pop up camper canvas, boat covers and camping chairs. It works on all heavy material including leather. Very easy to use. If you are an outdoorsman and don't want to throw something away because of a rip or tear the Speedy Stitcher is the tool to have. I just fixed one of my favorite camping chairs with it and thought I would pass the info along.
