Marking hammer (lumberman)
Lumberman's hammer bearing the stamp of the owner of the forest or of the
timber merchant, serving to mark felled trees on the cross-section. The
hammer may have a stamp on one or both sides, or there may be a metal wheel
on the handle bearing several letters or numbers so that a combination can
be stamped. The stamp hammer can be distinguished from the marking adze, as
it has no axe. See also the marking hammer of a tanner and the striking
punch. [MOT]
