Instead of focusing initially on the method the Blueprint irons would be manufactured, the initial work was studying what shape of iron elite players were demanding, paying particular attention to overall size and sole width across a number of different prototypes. The ultimate direction with the Blueprint was a more compact shape than any iron in Ping’s recent vintage with a narrow sole and much less offset. That tour feedback was validated when players like Tony Finau and Louis Oosthuizen put them in play months before the irons were going to be introduced.
