an outer structure having a first axis;
a blade having a retracted position in the outer structure and an extended position where the blade extends outwardly from the outer structure;
a blade actuating member configured to translate through the outer structure in directions parallel to the first axis;
wherein the blade actuating member is coupled to the blade and can move in a first direction to move the blade from the retracted position to the extended position; and
