Abstract
Abstract A razor blade assembly comprising razor blade means clamped between a platform member and a cap member. The platform and cap members are provided with dowel and aperture means by which they are connected together with the blade means held therebetween in assembled relationship, the dowels extending through holes in the blade means and the aforementioned aperture means and then expanded whereby to connect the assembly components together. The platform and cap members are further provided with runner means slidably engageable with complementarily shaped rail means of a razor handle.
