Antique Antler Sterling Sharpening Steel. Boasting a beautiful sterling silver collar, this antique sharpening blade is in excellent condition. We are unsure whether the antler hilt is bone or a manufactured antler, but seems to be actual antler. The end cap may also be sterling, but is without any mark and is moderately loose. The blade is tight and sturdy. Minor age-appropriate wear. This steel sharpening blade would make a lovely gift for your favorite chef.
