I carry a groove sharpening tool in my pocket when I play. When ever I want to play a spinny shot, I sharpen the grooves . This is after I remove any green or dirt from the club face and then the tool will sharpen and clean the grooves to give the ball that extra zip. A number of golf retailers carry such a tool and like your ball markers and tees, it goes into your pocket before the round. To get the ball to check is really effective when you chipping up the slope of the green and there is a little bit of moisture in the green. It is handy for chipping over undulations in the green or you want to run it over a tier and stop in dead.
