| 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. |  |
