How old are your Irons? How many rounds have you played with them?
Have you kept your grips clean? Are they worn? Do they fit your golf swing? 

Notice how we said: 
“Do they fit your golf swing?”; not just your hands.

Sure, a worn grip causes lots of problems in a golf swing. 

But, if you suffer from a hook, it could be minimised by making your grip thicker. It would slow the hands through impact.

?The size of hands AND your golf swing are factors in the grip that fits your clubs. 

New grips, that fit your golf game, help you to hit more accurate approach shots.

You can make your older set of Irons perform like new.

?Re-grip them. Hit better approach shots.
