Slingshot makers exist in great numbers. Many are of the small garage business type, run by a single enthusiast. This section concentrates on the larger factories that produce their slingshots in a more industrialized manner, and thus can reach the production rate that is necessary to meet the demand of large market chains. These slingshots are typically made of bent metal and / or plastics, and most of them carry tubular bands which are a lot easier to produce and attach to frame and pouch.
