A hand tool useful in forming a pocket mortise in the surface of a workpiece proximate an edge of the workpiece. The hand tool includes a clamping assembly for releasably clamping the tool to the workpiece, and a router carried by the clamp assembly and mounted for manual displacement toward the workpiece edge at an incline to progressively cut deeper into the workpiece and form an inclined pocket mortise. The hand tool also preferably carries a drill bit guide on the clamp assembly which is formed to receive and guide a drill bit from a hand drill for drilling a bore from the workpiece edge to the mortise. A method of forming a pocket mortise including the steps of clamping the clamp assembly with a movable router to a workpiece, routing the pocket mortise and then drilling a hole to the pocket mortise from the edge of the workpiece by a hand drill also is described.
