I bought a used set of Callaway X-12 irons. How do I know if the axles are steel or graphite?
Steel rods are usually unpainted, so it will be brilliant. In addition, steel shafts are generally "measures" in them - the diameter is about to change as you move down or toward the axis. Graphite shafts are usually painted black or plain. easy test: Compare trees iron on the shaft of his driver - the driver probably with a graphite shaft.
