Our Grozing plier is used for breaking glass along the score when it is too small for fingers or running pliers. The difference between these and normal pliers is that that the jaws only meet at the tip. This prevents the damage caused to the glass when the jaws of normal pliers close on the delicate edges. The shape of the jaws of these is also designed for grozing, which is the process of nibbling the edge of the glass to shape. Also useful for heaps of other jobs, these are pretty much indispensable for glass cutting. Instructions: 1.Break the glass by holding it's surface in one hand and holding the plier in the other hand. 2.Position the edge of the plier parallel to the score line, 1/4" away. 3.Apply a quick up and out motion. 4.To groze or remove unwanted edges from the glass, use the serrated jaw and nibble away glass. PS. The color of handle may be a little different as shown in the photo.
