Xcelite
Xcelite is a brand of hand tools geared towards the electronics service industry.[2] John Zilliox’s (1874-1971) U.S. patent 1,386,217 for an adjustable wrench, launched the company into manufacturing hand tools for worldwide distribution.The company marketed tools under the "XCEL" and, later, "Xcelite" brand names.By 1952, the Xcelite brand name was so well known in the electronics, television and radio repair industries, the company changed its corporate name to Xcelite, Inc.[4] In 1973, the brand was purchased by Cooper Industries.[5][6] In 2010, the brand was transferred to Apex Tool Group, a joint venture formed by Cooper Industries and Danaher Corporation.
