I, too find the anger about a fellow golf nut asking about a groove sharpener a little discomforting.
I now posit the following questions...
1) Which wedge of the formerly conforming groove construction seems to have the sharpest grooves?
2) How long can I play my formerly conforming groove construction wedges that everyone used to play not two years ago in my local member member? And can I rub it in when I two hop and check a pitch to my playing partner?... Do I get bonus points if they are a Sand Trap member?
3) Is it bad if I put a stripe of vaseline on my towel that gets swiped across my driver face before I hit?
And Most Importantly... Anyone who makes a bitter beer face to the previous three questions....
4) Can I hawkeye your approach and subsequent address and contact with the golf ball as you meet it in the rough or hell fairway... or hell marking and replacing the ball on your every shot?
I don't give a damn what you do... just play the ball down. Something many of the hecklers in this thread probably do not stay true to... Those guys aye carumbing a groove sharpener also probably wear black golf shoes with shorts and think it looks cool.
