Founded as a bright steel drawing plant in 1889, the company has continuously expanded the range of products it offers. It was this spirit that led BESSEY to begin production of manual clamping tools in the mid-1930s. Since then, the strength of its innovation has been underlined by the granting of numerous patents, for instance in 1936 for its malleable cast iron screw clamp, and in 2009 for the optimized all-steel rail profile. In 1979, with the takeover of Diner tool factory GmbH, a company rich in tradition, BESSEY established its cutting technology unit with the already popular Erdi snips.
