Modern shafts are built so that they can be used in long, mid & short irons. As the shafts
are cut shorter they get lighter, resulting in relatively heavier long irons & lighter short
irons.
To maximise power in the long game & accuracy in the short game, shaft weight must get
progressively heavier. This can only be achieved when each shaft is specifically made for
each club.

Evotech has over other conventional steel & graphite shafts.
