Leponitt 8" Metal Running Pliers for Stained Glass

Running pliers are one of the most useful tools in stained glass work — they let you run a score line cleanly and break glass pieces with consistent, controlled pressure. These durable 8" metal running pliers from Leponitt are built for the studio, with a lifetime guarantee on the pliers themselves (replaceable parts excluded).

How They Work

Position the curved jaw at the end of your score line on the edge of the glass, align the centering mark with your score, and gently squeeze. The curved jaw distributes equal pressure on both sides of the score for a clean, predictable break — no guesswork, no wasted glass.

Setting Up for a Perfect Break

Before you cut, set the running pliers on your glass and gently close them. Tighten the adjustment screw all the way down, then back it off about half a turn. This calibrates the jaw opening to just slightly less than your glass thickness — the sweet spot for a clean run every time.
