   A polesaw (also pole saw or giraffe saw) is a saw attached to a pole or long handle that is used for pruning tree branches that are beyond arm's reach. [1] [2] A polesaw allows its user to cut high branches without the use of a ladder. [3] Polesaws can be manual or motorized.

   When the pruners are open, the blade is longer than the anvil thanks to the eccentric bearing. When the pruners close, the blade draws back slightly while it pushes through the material. This reduces the cutting force needed to make a cut still further. Because they crush the stem they are cutting, anvil pruners are best for use on dead wood. [4]

   fig.2: Horizontal slide saw with open loop force flow fig.1: pivot saw with a close loop force flow. When a circular carbide-tipped saw blade enters or exits the material, only one tooth is cutting. The fluctuation of the load, when the tooth enters and exits the cut, induces vibrations and requires a very stiff gear box and machine.
