A second blade portion is rotatably movable about an axis near an end of the base blade opposite the first blade portion. The first blade portion and the second blade portion are rotatably movable relative to the base blade between extended and retracted positions. Each blade portion includes a selectably removable first pin and a selectably removable second pin. When installed, the first pin secures each of the first blade portion and the second blade portion in the extended position and the retracted position relative to the base blade, and when installed, the second pin secures each of the first blade portion and the second blade portion in the extended position relative to the base blade. |
