BTS (Basic Tool Supply)

BTS was a manufacturer of solid brass and german silver buckles founded in 1974. The company started out producing leather crafting tools which is the origin of the company's name. They quickly transitioned to making buckles and operated under the acronym BTS.

BTS also produced belt buckle "blanks" that were marketed to artists and used to create one of a kind buckles. They were often filled in with exotic hardwoods, stone inlay, resins, and carvings. They also collaborated with Steven L. Knight to produce a series of wildlife themed buckles.

The company was located in California and in later years (80s to early 90s) made buckles under the names Sunset Brass and Diablo Valley Associates. They also produced buckles for government agencies and police departments under the name The Buckle Works. The photos below show examples of the markings on several buckles.
