摘要： A razor-knife housing has a neat part retaining a blade and displaceable in the housing through a front-end slot between an extended position with the blade mainly outside the housing and a retracted position with the blade wholly inside the housing. A retaining part in slidable on the seat part between a closed position overlying the blade and holding it on the seat part and an open position exposing the blade on the formation and allowing it to be removed therefrom. The parts have faces normally engageable with each other to prevent sliding of the retaining part on the seat part. One of the faces is displaceable transversely to the other to allow the parts to slide relative to each other. In the extended position of the seat part and open position of the retaining part, the blade is is not retained on the seat part by the retaining part.

摘要： A utility knife has a flat blade formed with at least one throughgoing hole, a housing member forming a seat adapted to receive the blade, and a retainer member engageable with the blade on the seat. A pair of respective pivot elements on the housing and retainer members allow pivoting of the retainer member between a closed position engaging the blade and holding it against the seat and an open position exposing the blade and permitting its removal from the seat. Respective threadedly interengageable holding elements including a threaded screw on one of the members extending through the hole of the blade and a nut on the other of the members secure the retainer member in the closed position. The threaded screw is fixed in the housing member and has a threaded shaft projecting up from the seat. The nut is rotatable on the retainer member. The retainer member is formed with a large-diameter recess receiving the nut with radial play.

摘要： A utility knife for use with a flat blade having a pair of opposite faces has an elongated base part formed with an outwardly directed rear support surface, an outwardly directed front support surface separated longitudinally therefrom, and an inwardly directed intermediate surface between the support surfaces. The blade normally lies on the front support surface and projects longitudinally forward past the base part. An elongated cover part has an inwardly directed rear surface normally riding on the base-part rear support surface, an inwardly directed front surface normally pressing the blade inward against the base-part front support surface, and an outwardly directed intermediate surface. The cover part is displaceable longitudinally between one longitudinal end position with the intermediate surfaces transversely confronting each other and another longitudinal end position with the intermediate surfaces transversely out of alignment with each other. A biasing formation on at least one of the parts in the one longitudinal end position urges the cover-part intermediate surface transversely outward with a spring force into engagement with the base-part intermediate surface and thereby presses the front and rear cover-part surfaces toward the respective front and rear base-part surfaces.
