Abstract
A versatile ultrahoned sharpener includes a stop assembly which contains an inner hardened structure such as being made from metal or ceramic to serve as a positive limiting stop if the knife being sharpened cuts excessively into the plastic stop assembly of the sharpener. The sharpener also includes a manually actuated abrasive surfaced unit for cleaning or shaping the surface of at least one of the sharpening wheels in the sharpener. The sharpener further includes various bearing structures for effectively mounting the motor driven shaft which rotates the abrasive coated disks of the sharpener.
