The utility knife assembly includes a housing which extends in a longitudinal direction between opposite ends and presents an at least partially open interior. A blade with a sharp edge is fixed with the housing such that the blade extends through one of the longitudinal ends, and the blade is fixed with the housing in such a manner that it is non-movable relative to the housing. A blade protector is partially disposed in the open interior of the housing and is movable in the longitudinal direction relative to the housing between a retracted position and a covering position. In the retracted position, the sharp edge of the blade outside of the housing is exposed for cutting, and in the covering position, the sharp edge of the blade outside of the housing is covered by the blade protector.
