A high twig pruner, comprising an operating tube or an operating rod of a specified length (33); a saw blade (43) attached to the top end of the operating tube or rod to be movable in the forward and backward directions; a power source installed at the base end of the operating tube or rod; a drive means (80) connected to the power source to perform the forward and backward movements; and power transmission members (70A, 70) for connecting the drive means and the saw blade. The pruning part is formed in the saw blade (43), which is reciprocatory driven by the drive means (80). Thus the structure is simple, and the reduction of weight and size, as well as the improvement of workability in pruning, can be accomplished. <IMAGE>
