I have just bought a second hand set of 718 AP1's off ebay. I have received them and done the magnet test and it sticks to all parts of the head and shaft. Now this as alarmed me a little as I presumed this was not supposed to happen? There is a serial number etched into the hozzle on the 6 iron. I have emailed titleist but not sure if I'll get a reply.
Can anyone offer any advice on these irons?
