Assuming a sharp blade, the two main frustrations with pruning saws are inadequate handle and blade length.
This 13" pruning saw blade, coupled with a 39" handle, allows people of average height to cut branches that are 10' off the ground. The 6 tpi curved blade permits both under-cutting and over-cutting at height. Japanese-style tooth-tip bevels enable fast, clean cutting with a smooth start. Also, since the teeth cut on the pull stroke, blade distortion and user fatigue are minimized.
The blade (with two Chicago bolts for installation) is available separately for those who want to make custom handles, easily made from 3/4" x 1-1/4" stock (incidentally, a wooden hockey stick handle has those dimensions).
Blade made in Korea; handle made in USA.
