1. A miter saw comprising:

  • a base portion for supporting a workpiece;

    a sliding mechanism supported on the base portion;

    a cutter portion pivotally mounted on the sliding mechanism whereby the cutter portion is movable relative to the base portion on the sliding mechanism, the cutter portion being pivotable between a raised non-cutting position and a lower cutting position and adapted to rotatably support a circular saw blade; and

    a laser generator for projecting laser light focused into a line which is narrow relative to the width of a blade edge of the circular saw blade from a portion of the sliding mechanism proximate to the cutter portion, whereby substantially all of the laser light is projected below the circular saw blade when the cutter portion is in the raised position,wherein the laser generator is operable to project the narrow focused line of laser light onto the workpiece at any location on the workpiece adjacent to or directly beneath the position of the circular saw blade, andthe laser generator is arranged to slide with the cutter portion when the cutter portion slides relative to the base portion.
