SK Tools USA, LLC was founded in the early 1900s as the Sherman-Klove Company by Mason H. Sherman and Noah Grover Klove. In the early days, we specialized in contract work, producing tools and parts for other companies. After a brief period producing munitions and mortar shell casings during WWI, we returned to our true love and what still drives us today - manufacturing quality tools for the American technician. From the original Round-Headed Ratchet to the SK X-FRAME Ratcheting Wrench, we've been innovating for American professionals since day one.
