Having trouble with your approach shots lately? For irons that are used frequently, the grooves on the face can wear down over time, and the edges can also be worn away, reducing spin. This is especially noticeable on short irons and wedges. By repairing the grooves, you can improve your spin control. This is also recommended for those who haven't used their clubs in years, or for those who want to maintain used clubs they received. It repairs stubborn dirt and the grooves of golf clubs that have been crushed or have rounded edges. 【How to Use】 ① Hold the groove cleaner horizontally. Then, slide it little by little, being careful not to use too much force. ② The amount of material removed increases when the angle is raised and decreases when the angle is lowered. Adjust to your preference. ③ Adjust while shaving until you reach your desired depth (up to about 30 degrees to the floor). You can also search for "golf groove cutting" on YOUTUBE to find videos on how to use it.
