Abstract
A disposable razor has its head formed with a rearwardly directed pocket to receive the forward portion of the head of a second razor to its rear, so as to protect the cutting edge or edges of the second razor. The razors are firmly but releasably interengaged with each other by co-operating projections and recess.
