THUMBRING
Thumb ring
A thumb ring is a piece of equipment designed to protect the thumb during archery. This is a ring of leather, stone, horn, wood, ivory, metal, ceramics, plastic, or glass or which fits over the end of the thumb, coming to rest at the outer edge of the outer joint. Typically a flat area extends from the ring to protect the pad of the thumb from the bowstring; this may be supplemented by a leather extension.The above text is a snippet from Wikipedia: Thumb ring
