Used in joiner's shops for making a quick indentation to start screws or drills. To stop the point wandering off on a smooth surface. The one above is all metal, but in the main they seem to just have a wooden bar at the top making the tool look like a letter "T"

Some of them are quite small and the auger is barely evident, but ones with well defined awls on the ends like the one above are used for drilling through thin material like leather or thin plywood.

A nicely made Scratch Awl. These are used similarly to a scriber for making a more permanent mark than a pencil. In a similar way to a marking gauge the small recess that the tool makes gives a guide to the placement of a chisel.
