The pun in the title only works if you know how to say ketoh, which (in case you don’t) is ‘gay-toh’.
The history of the ketoh goes back to Navajo archers and the bands they wore to protect their forearms from the snap of their bowstrings. These stiff leather guards were eventually embellished by silversmiths with conchos, silver buttons, and turquoise stones. They ceased to be functional archery gear and instead became worn as decorative jewelry.
