STX (a contraction of the word "sticks" but commonly called "S-T-X") is a global sports equipment manufacturer based in Baltimore, Maryland, US.

In the case of Mr. Tucker, the situation was compounded by the fact that the vast majority of sticks were built and strung in such a manner that they were truly most conducive for right handed players.

With a desire to improve and grow the game they cherished, and access to the latest in raw material technology, Tucker and his partners began experimenting with various fabrications for a synthetic lacrosse head.

[6] Every single goal scored during the match was done so with an STX lacrosse head, a dramatic shift from just 12 months prior when wooden sticks were the standard.

In the mid-1970s, STX began branching out from lacrosse equipment with the development of golf putters, aided by ties with the chemical company DuPont.

[9][10] There are several NHL players who use STX gear, including Jiří Hudler, Matt Moulson, Vincent Trocheck, Ivan Barbashev, and Brandon Pirri.
