| 1. A miter saw comprising:
a base adapted to support a workpiece during cutting;
a motor;
a rotatable, circular blade driven by the motor, where the blade includes teeth around its periphery;
a pivot arm assembly associated with the base and supporting the blade above the base, where the pivot arm assembly is adapted
to pivot down toward the base to move the blade toward the base to cut a workpiece supported by the base, and where the pivot
arm assembly includes a handle adapted to be grasped by a user so that the user can move the blade down toward the base by
hand; and
a safety system having a detection subsystem adapted to detect an occurrence of an unsafe condition between a person and the
blade, and a reaction subsystem adapted to mitigate the unsafe condition, where the reaction subsystem includes a brake mechanism
adjacent the blade, and where at least a part of the brake mechanism is adapted to pivot into the teeth of the blade to engage
the blade.
