Description:
This is a clever little gizmo that is used to mark a board so that it will meet at a cross-board. It would primarilty be used for clapboard marking, but it's design allows it to be used in other situations as well.

This tool has a sliding knife much like the Nester's Patent gage (72,885 - 12/31/1867), but has the added feature of allowing you to gage and cut without removing the tool.
