A measurement probe edge guide tool includes an edge follower comprising two edge contact pins that spin around the outside of the measurement probe using a ball bearing. The edge contact pins hug the corner of a contoured edge of the workpiece or in-service part to provide a consistent distance of the center of the probe from the edge. The edge follower enables the tool to inspect the marginal portion bounded by a contoured (machined) edge of a workpiece or part. The edge follower is removable so that the tool may also be adapted for use in general acreage inspection. The tool features a spring-loaded mechanism with a positive probe protrusion relative to a roller-supported cage. The tool has either a handle which is coupled to the cage by means of a universal joint or a hand grip that is affixed to the cage.
