A hand-held cutting device (10) including an elongated member (45), a trimmer head (25), and a power unit operably coupled to the trimmer head (25) to selectively cause rotation of the trimmer head (25). The trimmer head (25) includes a line holding assembly (110, 310) to hold and selectively release trimmer line (70), and a housing to house the line holding assembly (110, 310), wherein the line holding assembly (110, 310) includes a core (140, 340), a line-release knob (160, 350), and a spool (130) configured to hold the trimmer line (70). The knob (160, 350) is axially movable with respect to the core (140, 340) between an extended first position and a retracted second position, the knob (160, 350) extending outwardly from the housing and being non-rotatably fixed to the core (140, 340) when the knob (160, 350) is in the first position. |
