I was wondering what the length of his irons were?

Rory's irons are standard length (6-iron = 37.5").

What are the length of his irons or at least the length of one of them?

Throughout the set.

Matt-

Apologies for the slow reply. The TK grind features a medium-wide sole with enhanced front-to-back and heel-to-toe camber making it versatile from a variety of turf conditions and face angles.  This grind influenced the sole profiles of the 58.04…

Does he say why he uses ribbed grips? Is it just his personal preference or does it help him in some way?

Thanks for the quick response!

Rory says he likes the feel and it helps him keep his grip as consistent as possible.

Does Rory use ribbed grips throughout his set or just his wedges?

Great player! Why does he use a 47° Vokey rather than the ZM Forged PW? What is the bounce on that 47° Vokey?
