This is a tool used to remove the clock knob on the 1967 and 1968 standard model. These knobs are held in with a small flat head recessed screw. These are designed to fit into the knob assembly without any play,and are milled to fit the screw slot. If you have ever tried to take these out with a jewelers screwdriver, you know how difficult they can be. These tools are made out of 316 stainless steel and have a aluminum handle.
*NOTE* These will strip out under excessive force so you will want to use penetrating oil first if your screw is corroded in place.
