Processes for treating cutting edges
First Claim
1. A process for microhoning the cutting edges of razor blades, said process comprising placing the edges in contact with a slurry of abrasive particles which have diameters of less than 3 microns and subjecting said slurry and said edges to sonic or ultrasonic energy from a horn or tool of a sonic or ultrasonic generator to cause said particles to hone said edges subjecting the edges to sonic or ultrasonic energy from the horn or too of a sonic or ultrasonic generator while said edges are in contact with a slurry of abrasive particles which have diameters of less than 3 microns.
