ABSTRACT:
A blade assembly for use in a razor has at least one blade providing a cutting edge, a leading skin guide located ahead of the cutting edge, and a trailing skin guide located behind the cutting edge. The leading and trailing skin guides are configured to provide one or more front contact surface and one or more rear contact surface, respectively, for contacting the skin of a user. These front and rear contact surfaces lie substantially on a virtual convexly-curved contact profile such that, when the blade assembly is pressed against the skin of a user, the skin becomes stretched to conform to the contact profile.
