How to Cut Plexiglass with a Utility Knife

Cutting plexiglass with a utility knife works best for making straight cuts in thin sheets of plexiglass (1/8 inch or less). But while a utility knife is convenient (you probably have one in your tool kit), Bolden does not love this method. “A sharp razor blade easily wanders across the surface of the materials,” she says. “Once [it] veers away from the straight edge, the plexiglass will not snap cleanly or straight.”

• Take the straight edge of your ruler and mark where you’d like to cut with a permanent marker.
• Place the plexiglass on a clean, sturdy work surface.
• Clamp a straightedge onto the plexiglass at the marked line.
• Wear utility gloves and safety glasses.
• Repeatedly score the plexiglass along the straightedge with steady pressure.
• Release the clamps and remove the plexiglass.
• Place the scored line of the plexiglass over a table edge.
• While holding the sheet firmly against the tabletop, apply downward pressure to the overhanging plexiglass until it snaps at the line.
• Clean up any rough edges with 120-grit sandpaper.
