Irons that have been used a lot will experience wear and tear over time, causing the grooves on the face to wear down and the edges to become rounded, which reduces spin. This is especially noticeable on short irons and wedges. Are you having trouble with your short game lately? Repairing the grooves can improve your spin control. This is also recommended for those who haven't used their clubs in years or who want to maintain used clubs they've received. It repairs the grooves of golf clubs that have stubborn dirt or whose edges have been crushed or rounded. You can also carry it with you during a round to remove unexpected dirt. 【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 it is lowered. Adjust to your preference. ③ Adjust and shave 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. 【Specifications】 Material: Metal Color: Blue Instant purchase without comment is OK.
