Abstract
Abstract A honing and sharpening machine for small tools and instruments such as those used by dentists, having a housing with an upper panel on which is mounted a reciprocal carriage for a honing or sharpening stone. The carriage is supported by a pair of end members rigidly mounted on the panel and is driven by a motor disposed in the housing beneath the carriage. The carriage and stone are reciprocated rapidly by the motor and the stone may be contoured to provide the optimum surface for shaping and reconditioning the tools and instruments.
