Black American patent

In 1896, a U.S. patent for a "Razor Stropping Device" was issued to black American inventor, Henry Grenon (No. 554,867). The invention combined a frame, a strop within the frame, travellers with horizontal movement along the frame, and a carrier mounted in the travellers to hold the razor blade. The device was designed to handle a razor while stropping it, and providing for the razor to automatically turn on its back when the direction of motion of the travellers is reversed.
