Steel KBS FLT120 Shaft, Lamkin Crossline Black Standard Grip. Progressive Spin Technology: The set incorporates different groove designs based on the iron number. V-Grooves on the 4-6 irons reduce spin, U-Grooves on the 7-PW optimize spin, and wedge-spaced grooves on the GW-SW (gap wedge to sand wedge) generate extra spin for shots around the green.
