Method of making folding hand tool set for bicycles

Abstract

A method for producing a tool for use in a folding hand tool set includes the following steps. Firstly, a metallic rod is provided. Next, a working end and a shank portion are formed on opposite ends of the metallic rod. The shank portion has a regular polygonal cross-section. The working end has a maximum external diameter (Z) is smaller than a maximum external diameter (Y) of the shank portion. Then, the shank portion is flattened into a flat, generally oblong portion by a stamping press, wherein the flattened shank portion has a thickness (X) more than or equal to a half of the maximum external diameter (Y) of the original shank portion. And the thickness (X) of the flattened shank portion is greater than the maximum external diameter (Z) of the working end. Finally, a hole is punched in an end of the flattened shank portion opposite the working end to complete the tool.
