Patent number: 5492038Abstract: A shaving system of the wet shave type includes support structure and blade structure secured to the support structure. The blade structure has an aperture with an annular sharpened shaving edge that is defined by main facet portions that converge at an angle of less than 40.degree., and supplemental facet portions that are extensions of the main facet portions and converge at an included angle of less than 60.degree. to define an annular ultimate tip portion. The annular ultimate tip of the sharpened edge defines a shaving plane and the bisector of the included angle defined by the supplemental facets is disposed at an angle (shaving angle) in the range of 15.degree.-35.degree. to the shaving plane.Type: GrantFiled: March 7, 1995Date of Patent: February 20, 1996Assignee: The Gillette CompanyInventors: Henryk J.

Patent number: 5067238Abstract: A shaving system of the wet shave type includes body structure that incorporates guide structure and fixed skin-engaging structure with skin-tensioning surface structure. Blade structure, carried by the body structure rearwardly of the fixed skin-engaging structure, has a cutting edge extending along the length of the body structure, and movable guard structure is carried by the body structure between and adjacent to the fixed skin-engaging structure and the cutting edge of the blade structure. The movable guard structure includes a series of skin-tensioning crest portions disposed for skin-engagement between and adjacent to the fixed skin-engaging structure and the cutting edge. The movable guard structure is positioned in the body structure in engagement with biasing structure for dynamic movement of the movable guard structure relative to the fixed skin-engaging structure against the biasing structure as guided by the guide structure in the course of shaving.Type: GrantFiled: September 28, 1990Date of Patent: November 26, 1991Assignee: The Gillette CompanyInventors: Gary R. Miller, Frederick R. Borden, Robert A. Trotta
