Abstract: A system for marking rotationally operated tools to indicate direction. Said tools incorporate green indicia to indicate clockwise motion and/or tightening of right hand threaded implements, i.e. nuts, bolts, screws, drill bits, pipes, fasteners, fittings, etc. and red indicia to indicate counterclockwise motion and/or loosening of right hand threaded fasteners fittings and other spirally operated implements. Also a tool marked as previously indicated.

Abstract: A body-supported hand-operated instrument desk which includes a pair of vertical frame members (20). A table surface is formed by a rectangular member (42) rotatably attached to the frame and a sold or resilient fabric table top (52) is employed to support a hand operated instrument such as a computer. A pair of shoulder straps (36) bridge across the frame allowing the device to be comfortably worn over the shoulders providing a platform that positions the instrument in a convenient location. The invention solves the problem of providing portable access to hand operated instruments heretofore unavailable.
