Abstract
A trimmer head for a hand-held cutting device may include a first housing portion, a line holding assembly to hold and selectively release trimmer line, and a second housing portion operably coupled to the first housing portion to house the line holding assembly. The line holding assembly may include a spool configured to hold the trimmer line and a core operably coupled to the spool. The line holding assembly may be configured such that rotational movement of the core causes corresponding movement of the spool, but movement of the core in an axial direction does not cause corresponding movement of the spool.
