Thank you for viewing! (^-^) This is an iron groove repair tool (groove cutter, groove shaver). Usable by both right-handed and left-handed players. The main body has a mesh pattern for a non-slip grip, and it comes with a cap for excellent safety (˃̵ᴗ˂̵) As you use your clubs, dirt can get into the grooves on the face, and the edges can become rounded, weakening the ball's grip. Try refreshing them with this product. It will definitely improve your ball's spin and control (^○^) Also, cleaning the grooves with this product after a round will help prevent deterioration due to rust in the grooves♪ 《How to Use》 ① Press the tool against the face grooves. ② While pressing against the grooves, slide it little by little. ※ Increasing the angle will increase the amount shaved, and decreasing it will decrease the amount (I think an angle of about 30 degrees to the face is good) ③ Shave until you reach your desired depth. I also have many other golf goods for sale. If you leave a comment, I can offer a discount and list them as a set, so I hope you'll take a look (^_^*) 〓Product List〓 #kuu-shop GOLF Backspin spin competition golf ball
