Patent number: 4265015Abstract: A razor in which a razor blade and a blade support, on which the razor blade is mounted, move together back and forth with respect to the base of the razor so as to adjust the contacting angle with respect to the operator's skin. The base is provided on the top of the handle of the razor, and the razor blade and the blade support are covered by a top plate mounted on the base. Provided in front of the blade support is a guard member which projects forwardly beyond the cutting edge of the razor blade and extends parallel with the cutting edge. The blade support and the razor blade are moved back and forth by a rotatable operating member. When the blade support is retracted backwards, the whisker particles clinging to the blade are scraped off and dropped from between the base and the guard member.Type: GrantFiled: June 27, 1979Date of Patent: May 5, 1981Assignee: Kai Cutlery Center Company LimitedInventor: Tamoru Asano
