In 2014, artist Billy Sprague of Oakland, California inherited his grandfather's leatherworking tools. He wanted to explore his own family traditions, so he began using them. As an avid bicyclist, he applied his emerging skills to bike saddle making. Sprague has since founded a studio called Obsidian Monarch, where he produces and sells leather goods, such as bike seats, guitar straps, and axe sheathes.
