To order the correct Axe Scabbard size, measure your axe from the bit to its hammer head. The axe should be about 1/8" smaller than the scabbard to work smoothly and freely. They fit most single-bitted axes without adjusting. Some old axes have rough spots. File or grind them off to let the axe slide in and out of the scabbard freely. Patented in U.S. & Canada.
