Abstract: A utility knife assembly includes a housing that has a first lateral wall, a second lateral wall and a perimeter wall extending between the first and second lateral walls. The perimeter wall includes a front wall, a rear wall, an upper wall and a lower wall. The front wall has a blade aperture therein. The upper wall has a slot therein. A tape measure tab is removably positionable in the slot. A blade is removably mounted to the housing and extends outwardly of the blade aperture. The slot is aligned with the blade to allow the tape measure to be used for measuring where the blade is cutting.
