A cutting device is disclosed. The cutting device has a housing and a carriage that is movably disposed in the housing, the carriage being movable between a retracted position and an extended position. The cutting device also has a cutting member that is removably disposable in the carriage, a cover member that is removably attachable to the housing, and an urging member that operably connects the carriage and the housing.
