Morton Safety Break System | Precision Glass Running Tool
Achieve flawless, predictable breaks on your scored art glass every single time. The Morton Safety Break (#SB01) is an essential, high-utility tool engineered for stained glass hobbyists and professional glass artists alike. Designed to eliminate the anxiety of tricky runs, flare-offs, and wasted sheet glass, this system provides exceptional control by applying perfectly concentrated, upward pressure directly beneath your score line.
Whether you are working with expensive textures, ripple glass, or running long, narrow strips, the Safety Break minimizes structural fractures and ensures a clean, straight split without the need for traditional running pliers.
Key Features & Benefits
- Flawless Glass Running Control: Acts as a specialized alternative to running pliers, using a unique push block and precision breaking button to gently guide the run right down your score line.
- Reduces Costly Glass Waste: Protects your investment by preventing erratic breaks, chips, and flares on cathedral, opalescent, or heavily textured art glass.
- Perfect for Narrow Strips & Small Cuts: Easily runs lines that are too thin or awkward for standard hand tools to grip effectively.
- Ergonomic, Low-Effort Operation: Ideal for glass artists who experience hand fatigue or have limited grip strength, using smooth leverage rather than brute force to break the glass.
- Seamless Grid Work: Integrates perfectly into your existing workshop setup, working beautifully alongside the Morton Portable Glass Shop layout blocks and waffle grids.
How It Works
- Position the Button: Place the small, round breaking button on your work surface directly underneath the scored glass line.
- Align the Block: Position the main push block over the top of the glass, directly straddling the score line over the button.
- Apply Pressure: Press down gently on the push block handle. The concentrated leverage forces the score to separate cleanly from underneath, giving you a perfect edge.

Morton Safety Break Components
The Morton Safety Break System relies on three simple, engineered components that work together to replace the uneven squeeze of traditional running pliers with perfectly centered, upward leverage.
By separating the pressure mechanics into three distinct parts, it ensures the glass breaks cleanly directly along your score line.
1. The Pressure Button (The Fulcrum)
The small, round plastic button is the hidden engine of the system. Placed directly on your workbench underneath the glass, it sits precisely centered below your score line. By acting as a focal point, it concentrates 100% of the upward force right into the weakest point of the glass score, forcing the run to start exactly where you want it.
2. The Specially Molded Push Block
The push block is the main hand tool you hold. Its underside features a distinct block profile designed to sit flat on top of the glass, straddling your score line. Because it covers both sides of the score evenly, it applies perfectly balanced downward pressure on either side of the fracture while the button pushes up from below. This balance prevents the glass from tilting, twisting, or flaring out to the side during the break.
3. The Dynamic Running Guide (The Lever)
The running guide or handle component provides the mechanical advantage. Instead of relying on raw grip or hand strength to squeeze a tool closed, the system allows you to use simple, low-effort downward pressure. By pressing down on the guide, you use the leverage of your workbench to gently and predictably roll the fracture all the way down the sheet, making it effortless to split long, narrow strips or tricky textures.
