Klein Tools Website

Since 1857, the company operated by Mathias Klein and his descendants to the fifth generation, has grown and developed along with the telecommunications and electrical industries where Klein pliers first found major usages. 

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, which is exhibited in a separate catalog.  

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. 

Like the industrial fields it serves, Klein Tools has grown dramatically since 1857. The world has come a long way since 1857. And 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 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. 

Klein remains dedicated to supplying only the finest quality products. Made for professional users, Klein tools are available through stock holding distributors worldwide.
