A member is rotatably mounted within the body about an axis substantially perpendicular to the longitudinal axis of the handle while a marking device, such as a blade, is mounted in a slot in the rotatable member. In a preferred form of the invention, a locking assembly releasably locks the rotatable member to the body at any desired rotational position.
