Patent number: 8117753Abstract: A safety razor blade unit has two or more blades (19,20,21) with parallel cutting edges (24,25,26) mounted in a frame (10) between guard and cap surfaces so that the average inter-blade span is not greater than 1.25 mm, and the wash through index, a measure of the rinsability obtained by a method defined in the specification, is not less than 0.20. The combination of narrow inter-blade spans and good rinsability enables enhanced comfort levels during shaving to be achieved.Type: GrantFiled: June 8, 2010Date of Patent: February 21, 2012Assignee: The Gillette CompanyInventors: Bernard Gilder, Ian Saker
