ABSTRACT:
An improved tree-pruning tool of the type known as a pole pruner, which features greatly reduced friction in operation. A cutting blade and an anvil are moved toward each other in a linear path. The blade is on top, so that the downward bending of the tree branch will tend to open the cut rather than to pinch the blade. Friction is further reduced by a novel cam-like engagement of the moving parts with a guide pin, which eliminates incidental lateral displacements of the cutting elements due to the geometry of the operating lever. The mechanism is simple, and may be made from stampings.
