4120 CHROMOLY WITH FLOW MICROSLOT (4-7 IRON)
A wider, longer micro-slot to create a more expansive high energy area of clubface – resulting in a higher flight and faster ball speeds.

INCREASED BOUNCE ANGLE
Increased by a degree in the long irons and 2 degrees in the scoring irons – for improved turf interaction.

WRAP AROUND SOLE GRIND
Heavy relief around the sole for improved turf interaction and seamless transition from micro slot 7 iron into traditional 8 iron construction

EXCEPTIONALLY COMPACT PLAYERS PROFILE
Dramatically reduced topline and blade length throughout the set.
FULL SATIN BRUSH
A less reflective, modern finish.
