1. A branch cutting saw comprising a saw body including at least a saw blade section and a grip section, and a sheath body operative to hold the saw body in a freely retractable manner and including a hook section for hooking onto a branch, the saw being configured such that the sheath body is manipulated to hook the hook section onto a branch and, while urging the hooked branch toward the saw blade section of the saw body, the saw blade section of the saw body is advanced and retreated to cut the branch, wherein
the hook section of the sheath body is pivotally supported at a leading end of the sheath body and is under spring bias to have a steady-state position in a longitudinal region of the sheath body, and is configured to be rotationally displaced from the steady-state position of the hook section when a load equivalent to or greater than the spring bias is applied against the spring bias, and
the saw blade section of the saw body is under spring bias to have a steady-state position at a position where a tip end of the saw blade section is retreated from the hook section, and is configured to be advanced from the steady-state position of the saw blade section when the grip section of the saw body is manipulated against the spring bias.
