Hey, there's absolutely no need to cut anything here. The rattle noise caused by the butt cap is a little too large for the handle, and this problem happens a lot with Babolat racquets. To fix it, remove the staples and remove the butt cap, use the quick drying glue and apply it on the handle (on the area where the butt cap fits in) and inside the butt cap. Remember that you must use a lot of glue to fill in. Wait for a few minutes before putting the butt cap back, and then the staples. Now let it sit for at least 6 hours to make sure it's completely dry before putting back the grip. 100% the rattle will never happen again. I fixed this problem twice on my Pure Storm GT.
