ABSTRACT OF THE DISCLOSURE A razor knife has an elongated housing formed of a front housing part and a rear housing part and having a longitudinally extending guide. The rear housing part is backwardly separable from the front housing part and carries a blade holder which has a seat for a razor blade and an actuator button exposed at a slot formed in the front housing part. This holder is displace- able by sliding of the actuator button from a back position with the blade wholly enclosed by the housing into a front position with a portion of the blade projecting forwardly from the housing. A tension spring inside the insert or back housing part continu- ously urges the holder into the back position. Interengaging formations on the operating button and the housing, however, allow the blade to be held in the outer position so long as a slight inward force is exerted on the slidable actuator button.
