The company prides itself with being a family-owned, blue-collar American company that believes in serving the hardest working tradesmen in the world, the American workers and craftsmen. It manufactures all of its products in America, using highest quality American steel only to forge its tools.〔http://www.skhandtool.com/carousel/made-in-usa.aspx〕 Jay Leno described SK as "an iconic American brand for decades," and the company is known for inventing the round-head ratchet wrench. == History == SK was founded as the Sherman-Klove Company, specializing in screw-machine products, by Mason H. Sherman and Noah Grover Klove. The company was founded in the early 1900s to supply munitions in WWI, and made mortar housings in a screw machine plant on Harrison Street in Chicago. During the 1920s SK operated primarily as a contract company, making tools for other brands (including Craftsman).〔(【引用サイトリンク】title=Sherman-Klove and S-K Tools )〕 Business thrived, they made specialty screw machine products that did well until the depression. William S. Sherman (W.S.), Mason's son, came to SK after graduating college in 1927 and was eventually a major owner of the company. One of the products the company made was socket wrenches for Hinsdale Socket and Wrench Company. The Hinsdale Company went out of business during the great depression leaving Sherman-Klove with a large inventory of this product, they then redesigned the product and changed the company name to S-K Tools. Theodore Rueb, an engineer for the Sherman-Klove Company, went on to developed a new mechanism for a very successful line of ratchets, scaled from 1/4-drive up to 3/4-drive. The "round-head" ratchet has remained one of the most popular ratchet styles in the seven decades since S-K's first development, and many modern ratchets are little changed from the earliest design. SK invented the round-head ratchet wrench in 1933 and received a patent for it the following year, which remains a mainstay of their, and every major competitor's product line today. In 1962, SK, along with manufacturing partner Lectrolite Corp., of Defiance, OH was bought out by Symington-Wayne and became SK Wayne. In 1968 S-K Wayne was purchased by Dresser Industries as part of the merger between Wayne Oil and Tank Company and Dresser Industries. Dresser Industries made many changes to S-K's tools including dropping the cross-hatch pattern from their sockets in order to 'modernize' them. In 1985, SK became part of Facom Tools.〔 On June 29, 2010, the company declared bankruptcy. On August 23, 2010, it was announced that two days later, on August 25, 2010, Ideal Industries would acquire SK. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「SK Hand Tools」の詳細全文を読む スポンサード リンク
