STX (sports manufacturer)
STX (a contraction of the word "sticks" but commonly called "S-T-X") is a global sports equipment manufacturer based in Baltimore, Maryland. It is a subsidiary of Wm. T. Burnett & Co. STX makes lacrosse equipment, field hockey equipment, ice hockey equipment, and golf putters, but its main business is in manufacturing of men's and women's lacrosse sticks and protective gear, including gloves, pads, and women's eyewear. The company was founded in 1970 by Richard B.C. Tucker, Sr. as STX Inc. STX's first stick was the double wall, synthetic lacrosse head (U.S. Pat. #3,507,495), which was the first synthetic stick and the only type used to score goals in the first NCAA Men's Lacrosse Championship (1971).
STX is one of the largest manufacturers of lacrosse equipment, and in Maryland, part of the $66+ million industry.
