Abstract
A new blade for a shaver is disclosed with a profile where a single sided of the blade, rather than a dual sided blade, is ground to make a cutting surface. Such a single sided blade, or “chisel blade” has been found to have important advantages in scrubbing razors in particular, but in general for replaceable razor cartridges, whether used in scrubbing razor configuration or single cartridge applications.
Claims13
An improved shaver having a handle and a cartridge carrying a plurality of blades, comprising:
- a razor blade having a profile including a first surface that is planar along an entirety of the surface, and a second side having a first portion that is planar and parallel to the first surface, and a ground second portion that reduces a thickness of the profile in the distal direction until it reaches the first side to form a cutting edge at the distal edge of said blade.
An improved razor blade, comprising:
- a razor body having a profile including a first surface that is planar along an entirety of the surface, and a second side having a first portion that is planar and parallel to the first surface, and a ground second portion that reduces a thickness of the profile in the distal direction until it reaches the first side to form a cutting edge in the distal edge of said blade.
The improved razor blade of 11, wherein transitions between the linear sections form apices.
