Step 5: Hit the ends
Once your cutting path is made, use a wooden tool handle and strike without forcing too much on both ends of your cut.

Place your tempered glass on the wooden handle of your tool so that it is not entirely on the ground. Place your two hands parallel to each side of the glass and break the glass by pressing on both sides simultaneously.
If you feel that the glass is not coming off, it is better to redo a line with your glass cutter rather than forcing it.
