Since 1857, the company operated by Mathias Klein and his descendants to the sixth generation, has grown and developed along with the telecommunications and electrical industries where Klein pliers first found major usages.
When Mathias Klein emigrated from Germany and made his way west to set up shop in Chicago’s bustling downtown business district, the “communications industry” amounted to nothing more than a few bare wires strung on lean telegraph poles.

Perhaps the only job Mathias Klein ever did “halfway” involved the first tool he ever made, which was — in fact — one half pair of pliers. A broken side-cutting pliers was brought to his forge shop by a telegraph lineman. Mathias Klein forged and finished a new half for the tool, riveted it to the old, and the lineman went on his way. Shortly thereafter the lineman returned. The other original half of the tool had now broken and Mathias Klein forged the second pliers half, producing the first complete Klein pliers.

Today, Klein Tools, Inc. represents much more than Klein pliers. The company’s product line has broadened to include virtually every major type of hand tool used in construction, electronics, mining, and general industry in addition to the electrical and telecommunications fields. Klein Tools also supplies a line of occupational protective equipment.

Internationally, Klein’s products are available around the world through a well-established network of agents and distributors who stock the products that are required for their particular markets. Klein’s reputation as a leading producer of professional-quality products is global.
Today, the Klein brand is the #1 preferred hand tool in the electrical industry, as well as one of the leading brands used in the maintenance, construction, and industrial trades. Loyalty to Klein Tools is strong due to Klein Tools’ commitment to professional tradesmen and professional users; professionals feel the difference every day.

The world has come a long way since 1857. Klein has become a multi-million dollar manufacturer … yet a company still concerned about meeting professional needs – and making products to professional-quality standards. Klein remains dedicated to supplying only the finest quality products.

Klein Tools is still owned and managed by the Klein family. Direct descendants of Mathias Klein are actively engaged in every aspect of the business. Its products are still sold through distributors who serve the professional tradesman. And Klein Tools still makes dependable, efficient, and durable tools and equipment. Nothing less than the best to equip the professional.
