Klein Tools was founded in 1857 by an industrious German immigrant, Mathias Klein, who began in the hand tool business when a broken side-cutting pliers was brought to his forge shop by a telegraph lineman. Mathias repaired the pliers by forging and finishing a new half for the tool and riveting it to the old half. Soon the lineman returned because the other original half of the pliers had broken and needed replacement. Mathias forged and finished the second half of the pliers and riveted it to the other replacement half – creating the first complete Klein pliers.

To this day, Klein Tools is proudly owned and managed by the Klein family. Over 150 years of hard work and dedication has earned Klein the reputation of supplying only the finest quality products for users of professional hand tools and occupational protective equipment..

These days, it can be hard to find companies that make products you can count on. But that’s exactly what you’ll get from Klein Tools.

They don’t just make great products, they make great products that stand up to the demands of the professionals who use them everyday. Because their standards are as high as yours, they demand that every one of their hand tools delivers all the performance, durability and precision that you need to get the job done right.
