Henry Gomph produced tools in Albany, NY under the Gomph name from the later 1860s through the 1920s. Gomph tools were among the most highly regarded tools of their day by professional leather tradesmen, and their quality and durability carries through today. This is an overstitch wheel, designed for marking stitch hole locations on leather. It has a metal wheel with sharp points that go all around it. When rolled onto the leather, the points leave a slight impression in the material, serving as a perfect guide for pricking or stitching later on, especially in a straight line. In very nice unrestored vintage condition; 6" long, brass ferrule, hardwood handle, clear markings.
