​Unlike​ running pliers, grozing pliers are used with the flat tip butted up against your scoreline.
​Squeeze the pliers until you have a firm grip on the glass but not so hard that you crush it. Maintain this pressure throughout the rest of the directions. ​​
​Get a steady grip on the glass with your free hand.
​The method of breaking the glass with grozing pliers is by pulling the piece of glass off of the rest.
