Keep your grooves fresh!
Look, grooves on their own don't create spin. What they do is, they push dirt, grass, and other debris away from the clubface, so it can create friction, which does create spin.
As a wedge or iron gets older and frequently used, the grooves lose their depth. That means that less gunk gets pushed away, and less friction is created.
That means less spin...
This groove sharpening tool helps prevent that!
Not only does it clean your grooves, but it will also add any lost depth back.
Keep your golf balls checking up on the greens!
