A barber or straight edge razor houses a replaceable blade and includes a body member having a handle and a blade-receiving base portion, a clamp member detachably hinged to the base portion to comprise opposite halves of the razor, and bias apparatus between the razor halves above the hinge for urging the lower portions of the razor halves relatively toward each other to retain the blade therebetween. The blade is releasable by moving the upper portions of the razor halves relatively toward one another. Along a rear gripping portion of the razor halves, one of the halves is structured to assume substantially all of the normal gripping forces so as to prevent inadvertent release of the blade, while the halves include a forward region which is structured to receive special pinching forces to release the blade. Upwardly and rearwardly inclined ridges in the blade-retaining region may be provided to aid in upward seating of the blade as it is moved rearwardly into the razor. Also, the hinge pivot pins may be integral with one of the razor halves and hinge tubes are integral with the other.

A barber-type razor for housing a replaceable blade comprising:
A barber-type razor for housing a replaceable blade comprising a body member having a handle and a blade-receiving base portion forwardly of the handle, a clamp member hinged to the base portion by means of a hinge between and extending longitudinally of said base portion and said clamp member, said base portion and said clamp member comprising opposite halves of the razor, said hinge being located between the top and bottom portions of said base portion and said clamp member, a blade-seating region existing below said hinge for receiving a blade introduced thereinto from the front of the razor, said seating region having at least an upper limit thereto and being open at the bottom to permit blade removal, bias means for yieldably urging the bottom portions of said razor halves relatively toward one another to retain a blade therebetween, said bias means yielding to permit relative rotation of said clamp member to allow said introduction of a blade and removal of a blade, and said blade-seating region including means for engaging and relatively upwardly moving a blade and aiding the seating thereof at said seating region upper limit as the blade is moved rearwardly into the seating region.
