Domingo Zubiaurre, a member of a family of polishers from Eibar, Spain, decided to start manufacturing wire brushes, a product that he knew well from his trade as a polisher for the important local gun industry. His humble beginnings started in a small garage on Arragueta Street until the Spanish Civil War then moved to a different location on Legarre Street. From 1924 to 1957, JAZ’s activity was modest and specialized, dedicating itself exclusively to a single customer: UNCETA, an industrial distributor also located in Eibar, founded in 1874 and specialized in selling tools for the growing industrial market in the area and surrounding towns.
