Patent ID: 7488241

Claim:
In a knife sharpener for creating ultra sharp, smooth and polished edges by stabilizing the position of the knife edge as it is sharpened, comprising a motor driven symmetrically shaped abrasive surfaced disk mounted on a rotating shaft for sharpening a knife with one or more edge facets adjacent its two knife faces, said abrasive surface comprising ultrafine particles less than 0.002 inch in diameter, said disk surface having a truncated cone shape modified with its conical sloping radial side surface slightly crowned in a direction nominally perpendicular to the rotational circumferential line of contact on said disk surface with the knife facet being sharpened on that abrasive surfaced disk, said disk mounted opposite an elongated precision angle guide for sustained sliding contact with the face of the knife to position a knife edge facet in precise angular contact solely with the crowned area of said abrasive surfaced disk, said disk mounted to a hub, and said hub being mounted displaceably slidingly along the motor driven shaft against a resilient spring-like element with a force less than 0.2 pound to maintain sustained abrading contact with the facet.
