Irons that have been used a lot will experience wear and tear over time, with the grooves on the face wearing down and the edges of the clubface also becoming rounded, reducing 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 are using their clubs for the first time in years, or for those who want to maintain used clubs they received as a gift. It repairs the grooves of golf clubs that have stubborn dirt or have been crushed or have rounded edges. You can carry it with you during a round and use it to remove unexpected dirt. 【How to Use】 ① Hold the groove cleaner horizontally against the clubface. 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 the angle and shave until you reach your desired depth (up to about 30 degrees relative to the clubface). 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.
