The Grozier Plier
It's bigger brother the running plier gets about 90% of the use while cutting and breaking glass, but there are a few things the grozier pliers can do that the running pliers cannot. The grozier is best suited for breaking off very thin lines down the side of a piece of glass. The grozier also excels at breaking out inside curves, as the running plier's breaking powers cannot turn corners.
