Bracer

A bracer (or arm-guard) is a strap or sheath, commonly made of leather, stone or plastic, that covers the ventral (inside) surface of an archer's bow-holding arm.

The modern Navajo people and Hopi developed a form of bracer known as a ketoh, which can be decorated with silver, turquoise, and other adornments, possibly from earlier examples made of bone.

Ketohs may have a smooth leather surface on the inside of the arm and are then functional, but they are normally used as items of personal and ritual adornment, or as works of art in their own right.

[2] A review identifies two major sources of stone from which they are made, suggests that they may well not be connected with archery, and highlights other potential uses.

In many common role-playing games, bracers are a general piece of armour rather than protective archery equipment, possibly due to confusion with vambraces.
