ABSTRACT:
An instrument for sharpening microtome knives and similar articles, having a honing mechanism and a deburring or stropping mechanism, arranged on a housing which encloses motors for driving the mechanisms. The knife is honed against a stone, which is mounted on a reciprocating carriage that has a variable speed control, and the honed knife blade is then deburred or stropped using a pair of counter-rotating disks, one for each side of the knife blade. A vise securely holds the knife and positions it at the proper angle for optimum honing, and the vise is mounted in a track which allows the knife blade to be moved back and forth across the reciprocating hone for uniform honing. A shield guards against inadvertent contact with the dangerously sharp blades during the honing operation, and guards are used to prevent the vise from leaving the track.
