Abstract
A treatment device for improving the cutting properties of the blade of a non-electric shaving razor. The device has a treatment surface for interacting with the cutting edge of the razor blade, as the blade is put into sliding contact with the treatment surface. The treatment surface has a plurality of resilient honing projections that are compressed as the blade is moved in sliding contact with the surface.
Claims39
A device for treating a blade of a manual razor, the blade having a cutting edge, the device comprising:
- a. a treatment surface made of resilient, non abrading material for interacting with the cutting edge when the blade is in sliding contact with the treatment surface, the treatment surface including a plurality of resilient projections having a base portion and a tip portion;
- b. the resilient projections defining a discontinuous contact surface with the blade during the sliding contact.
A method for treating a blade of a manual razor, the blade having a cutting edge, the method comprising:
- a. providing a treatment surface including a plurality of resilient projections with a base and a tip portion;
- b. moving the blade and the treatment surface one with relation to the other such that the cutting edge is in a sliding contact with the resilient projections;
- c. pressing the manual razor and the treatment surface one against the other during the sliding contact such that the cutting edge compresses the resilient projections and defines a discontinuous contact surface therewith so as to provide a treatment of the cutting edge by substantially restoring an original shape of the cutting edge rather than by an abrading action.
