Abstract: A butt-end apparatus for a lacrosse stick or other sport implement. The butt-end apparatus comprises a hand abutment comprising: a handle-facing surface to face a handle of the lacrosse stick or other sport implement; and a hand-engaging surface to engage a hand of a player when holding the lacrosse stick or other sport implement. A position of the hand-engaging surface along the handle relative to a longitudinal end of the lacrosse stick or other sport implement is adjustable. An end cap may be mountable to a longitudinal end of a shaft of the lacrosse stick or other sport implement to define the longitudinal end of the lacrosse stick or other sport implement.
