Abstract
A knife includes a handle having a blade containing portion for mounting a substantially flat blade, an opening in a terminal end of the blade containing portion through which an end of the blade can project, a blade retainer inside the blade containing portion, having a first projection selectively engagable with a corresponding cutout in the blade for removably retaining the blade, and a blade release member having a second projection. The blade release member is mounted in the blade containing portion and movable in a direction substantially perpendicular to the major plane of the flat blade such that the second projection contacts and flexes the blade to disengage the first projection and the blade cutout to disengage the blade retainer from the blade. This allows removal of the blade from the blade holder via the opening.
