The OnCourse Groove Cleaner is a simple, handy tool for keeping your clubs performing at their best. Dirt, sand, and packed grass can build up in your clubface grooves during a round, and clean grooves help you get more consistent contact, spin, and control on your approach shots. This groove cleaner makes it easy to clear that debris away between shots, so your irons and wedges are ready for the next swing. Compact and easy to carry, it’s a practical accessory for golfers of every skill level and makes a great low-cost gift.
