Klein Tools - For Professionals Since 1857

No other hand tool company can make claims about their heritage, craftsmanship, or lifelong American roots quite like Klein can. Since 1857, the Klein name has stood for precision craftsmanship, day-to-day durability and performance. The name on our tools is not just the name of the family that owns it, it’s also our reputation and our promise of quality craftsmanship, built in America.
