Studio Pro Breaking and Grozing Pliers are a handy double duty tool and a must for the art glass enthusiast. When glass can’t be handled comfortably by hand, use the breaking pliers to safely break the glass along the score line. Turn the pliers over and use the pliers as grozers to nibble glass away from edges to reduce your grinding time. The 3/8” wide jaw provide leverage to securely hold the glass and the spring-loaded jaws work easily and reduce hand fatigue.
