For my Project I created a changeable end for a handle so you can change a flat head screwdriver to a hammer in a few simple steps. Simply by removing the pin from the handle you can take out the old end and replace it with the desired end by placing the desired end, six sided male end, into the handle, six sided female end. Next you take the pin and slide back in to the same position until the half-circle on the pin reaches the half-circle hole in the handle. This tool will lower the amount of equipment needed and more ends can be designed as they may be needed.
