A pole saw includes a long handle with cast end adapter, a cast saw-holding component pivoted to the end adapter for movement between an extended use position and a handle-adjacent storage position, and a saw blade pivoted to the holding component for movement between a blade-use position and a blade-protected position. The end adapter and holding component are cast aluminum for strength and light weight, and are pivoted together about an offset axis so that the blade and blade-holding component are positioned adjacent the handle in a partially protected position that is very compact; thus, no disassembly or separate tools are required. A folding lock mechanism includes a hook and pressure pad that cooperate for secure locking in the extended use position. An adjustable set screw eliminates blade looseness when in the use position. |
