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.
Claims27
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 having a base portion and a tip portion said treatment surface having an edge direction and a direction transverse to said edge direction, the resilient projections having a height less than about 1 millimeter and being arranged on the treatment surface to have, in a length of 1 millimeter in said transverse direction, a number of resilient projections in the range from 1 to 5;
- b. the resilient projections defining a discontinuous contact surface with the blade during the sliding contact.
