Patent ID: 7073412

Claim:
A method of forming an enclosed pawl pocket that is integral with a neck portion of a wrench, the wrench having a handle and a head integral with the handle and defining the integral neck portion between the head and the handle, wherein the head defines a bore having an axis extending between a first side of the wrench and a second side of the wrench, and wherein the bore has an opening to at least the first side, said method comprising the steps of: providing a keyway cutter having a planar cutting head disposed on an elongated pin having an axis, the plane of the cutting head being perpendicular to the pin axis, and having a radius defined in the plane of the cutting head between a center of the cutting head and the outermost edge of the cutting head being less than a radius of the bore; disposing the keyway cutter within the bore through the opening so that the cutting head is in an operating plane that is perpendicular to the bore axis; while maintaining the cutting head in the operating plane, moving the cutting head into the neck portion along a predetermined path so that the cutting head cuts the pawl pocket into the neck portion, the predetermined path defining at least two flat surfaces on respective opposing sides of the pawl pocket, each of the flat surfaces defining an angle in the range of about 27 to 35 degrees between a centerline of the pawl pocket and the flat surfaces.
