A hand-held power working machine which is capable of reducing the weight of the clipper blades, capable of being suitably heat-treated in the manufacture thereof, and capable of minimizing the stress concentration at the slot portions during the operation thereof. The clipper blades comprise a large number of cutting edges, and a large number of slots formed along a full length of each of the clipper blades; wherein the pitch of array of the cutting edges is substantially the same as the pitch of array of the slots.
