Klein Tools is the result of one of those “happy accidents” that turn out to be revolutionary. Klein Tools famously got their start in 1857 when a linesman came to founder Matthias Klein to repair his broken pliers. Klein replaced the broken half and when the old half of the tool broke too, Klein forged a replacement for that, thus making the first Klein Linesman pliers. Since these humble beginnings, Klein Tools has grown and become one of the largest American made toolmakers and they’re a brand used by tradesmen, linesman and electricians all across America.
