About SK Professional Tools
SK Professional Tools has manufactured precision hand tools in the United States since 1916, producing ratchets, sockets, and wrenches in Williamsport, Pennsylvania using American steel and the company's signature SuperKrome finish.
Heritage & History
Mason H. Sherman and Noah Grover Klove founded the Sherman-Klove Company in Chicago in 1916, beginning as a screw-machine products manufacturer. The company pivoted to tools after WWI and in 1934 earned a federal patent for its signature round-headed ratchet wrench — an SK engineer named Theodore Rueb designed the mechanism that became the foundation of the brand's professional reputation.
SK Professional Tools has changed ownership multiple times over its century of operation, but the commitment to American manufacturing has been maintained through each transition. In 2021, the company relocated its manufacturing and distribution operations from Sycamore, Illinois to Williamsport, Pennsylvania, where it continues producing tools to the same precision standards that have made SK a trusted name among professional mechanics and tradespeople.
Made in Williamsport, Pennsylvania
SK Professional Tools produces its sockets, ratchets, and hand tools at its Williamsport, Pennsylvania facility using cold-forged American steel and the brand's SuperKrome finish — a high-polish chrome plating that provides both corrosion resistance and the smooth surface finish that makes tools easy to wipe clean in shop environments. The cold-forging process aligns the grain structure of the steel, producing tools stronger than those made from cast alternatives.
The 6-point and 12-point socket designs are engineered to minimize slip on rounded fasteners, a practical engineering choice that reflects the professional use case SK tools are designed for. For mechanics who depend on their tools to perform reliably under professional use conditions, SK's American manufacturing and century-long engineering history provide the confidence that imported alternatives often cannot.
