Abstract:
1. A razor handle having a front end, a back end opposite the front end, an upper surface, a lower surface corresponding to a razor blade edge and opposite the upper surface, and a length in a longitudinal direction defined between the front end and the back end, the razor handle comprising: a head portion for connection to a razor head; and a body portion for hand grasping of the razor handle; wherein from a side view, the shape of the upper surface is arcuate in the longitudinal direction along the entire length of the razor handle and has a radius of curvature that continuously increases along the length of the razor handle, from approximately 2 cm at the back end to approximately 20 cm at a median location located at approximately half the length of the razor handle, and that continuously decreases along the length of the razor handle, from the median location towards the front end; wherein from a side view, moving along the length of the handle in the longitudinal direction beginning adjacent the head portion, the shape of the lower surface transitions from concave and smooth to convex and including a first plurality of projections of a first material thereon to concave and smooth proximate the median location of the handle to convex to concave and including a second plurality of projections of a second material thereon to convex and smooth at the back end; wherein from a side view, the upper surface and the lower surface define a height of the razor handle therebetween, and apart from the front and back ends, the smallest height of the body portion is located at approximately two thirds of the length of the body portion from the back end; and wherein the radius of curvature of the upper surface is always positive.
