    Step 6: Cut your tempered glass in half

    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.
