  • Apparatus and method for testing an edge of a workpiece for sharpness
    Publication number: 20120090390
    Abstract: An apparatus for testing an edge of a workpiece for sharpness includes a body, a probe extending outwardly and pivotably mounted from the body, the probe is biased in a direction for placement against an edge of a workpiece with a predetermined force, a test head on a distal end of the probe for mounting test tape for physical contact with an edge as a test medium, a test point for mounting to the workpiece, and a continuity circuit mounted to the body in electrical communication with the test head and the test point for providing a predetermined electrical current between the test head and the test point through the workpiece when the test tape is cut sufficiently by the workpiece to allow the test head to touch the workpiece to form a complete circuit.
