A cutting tool is disclosed with an elongated, hollow first handle. An extension mechanism fixed with the first handle's distal end features a housing with a blade slot and blade connected with gears rotationally fixed with the housing. The proximal end of the housing's extension rod slides within the first handle, and its distal end terminates at a rigid hook with a first gear rack that engages the pinion gears. The cutting tool is suited for safety and ease-of-use in small, tight or otherwise difficult to reach environments.
