Hey guys i tried looking through the forum but cant find much stuff, need some enlightenment from you all> Ok so, i find it REALLY hard to remove grommets, especially ones which definitely need replacing. I tried it with awls, pliers and cutters, from the inside and outside of the racquet too.:crying: Wondering how one go about using a grommet grinder, and are they effective and safe (for racquet) to use? i also notice 3mm and 4mm sizes, would i need both sizes just for badminton ?? Thank you all very much !
