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.
Claims41
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 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 with a base portion and a tip portion defining honing resilient projections;
- b. the resilient projections defining a discontinuous contact surface with the blade during the sliding contact and acting as honing rods.
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.
In combination, a safety razor and a device for sharpening or cleaning the safety razor blade, the device comprising a polymer-based mat section comprising at least one substantially plane surface having a length to receive a head of the safety razor as the safety razor blade is slid across the substantially plane surface of the mat in a direction opposite the shaving direction to condition the safety razor without abrasive or polishing material on the mat.
A method for sharpening a safety razor blade, the method comprising the steps of:
- a) providing a polymer-based mat, the polymer-base mat comprising at least one substantially plane surface,
- b) providing lubricating material on at least part of the substantially plane surface of the mat, and
- c) sliding the safety razor blade across the substantially plane surface of the mat in a direction opposite the shaving direction, the safety razor blade being moved in a manner so that at least part of the lubricant material is distributed over at least part of the substantially plane surface of the mat, wherein contact between the mat and an edge of the blade conditions the blade edge without abrasive or polishing material on the mat.
