Abstract
A pruning saw having an arcuately shaped housing which guides a flexible saw blade as the blade moves back and forth within the housing. The saw blade is comprised of toothed blade segments, pivotally fastened together. Each segment has its teeth bent or set to produce a kerf which is greater in width than the width of the housing.

An improved saw for use in manually pruning a tree limb comprising:
- an arcuately shaped housing having a substantially hollow interior and a circumferential slot therein facing toward the center of the arc thereby forming a channel,
- a plurality of saw toothed blade segments pivotally attached end to end in serial fashion so as to form a single flexible saw blade and being slidably positioned in said channel with the teeth extending through said slot,
