Stained Glass Tools

Choose running or grozing pliers

Decide whether the work needs a scored sheet opened or a small edge adjusted.

Start with the cut you want to open

Running pliers are designed to open an existing score. Check the locating mark, jaw style and stated glass thickness. The Bohle BO700.0A uses an adjustable bar and disk, with a stated thickness range up to 5 mm.

Compare the jaw at the edge

Grozing means nibbling small amounts from the edge. Compare jaw width, the shape of the contact surfaces and how much room you have around the piece. A short or narrow jaw can solve a different access problem than a long handle.

Check multi-purpose models by their exact code

Fletcher’s 06-111 and 06-112 use interchangeable jaws to switch roles. The model number distinguishes the six- and eight-inch bodies. Check the pack and exact jaw parts before choosing it to replace two dedicated tools.

Guide questions

Can I compare pliers by their overall length alone?

Compare length for hand and workpiece access, then look separately at jaw geometry and the glass thickness each tool supports.

What do I compare for narrow strips?

Look at the jaw width and pressure mechanism, then check the permitted glass thickness and room along the score.

Do two pliers in a kit always do different jobs?

Read each tool’s description. Look for a running jaw and a grozing or breaking jaw if you want separate functions.

Which accessory suits the job?

  1. Studio Pro 600 is built around a curved running jaw and the score alignment mark. The 601 gives you a narrower jaw for local breaking and trimming at the edge.

  2. The 600LW has a polymer body and replaceable tips. The BO700.0A uses an aluminum body and adjustable pressure parts. Compare the two jaw systems for the score you need to open.

  4. Compare the Studio Pro 601’s 3/8-inch jaw with the GlassPro 2202’s 1/8-inch jaw. The space available at the edge determines which contact size makes sense.

  5. Tillery’s quarter-inch and 3/8-inch jaws cover different amounts of the edge. Compare the room around the cut before selecting the wider tool.
