The invention relates to a curvilinear saw efficiently using all its teeth disposed all along the saw blade for the smooth handling of the saw while cutting. The saw blade 1 forms a curve going from one extremity to the other of the front end of thesaw. A plurality of teeth 2 are shaped on the hollow edge of the blade so that the angles formed by the teeth 3 set in proximity to the rear edge of the blade are relatively greater than same angles set next to the front edge of the blade in relation to the point line 5 connecting the edges of the teeth 4. This makes possible the construction of a saw, especially of a pruning saw, using efficiently all its teeth disposed all along the saw blade so that cutting is smoothly carried out with constant force. |
