What Customers Are Saying

Customers praise this tool for cleanly cutting acrylic, plexiglass, and polycarbonate sheets, with many noting it cuts "like butter" and makes clean lines when used correctly with a straightedge and firm pressure. Most find it affordable and effective for light diffusers and poster frames. However, a significant portion report durability concerns, describing the tool as flimsy with blades breaking on first use or plastic bodies snapping under pressure. Several advise buying something sturdier, noting it won't last long despite initial performance. Overall, reviewers recommend it for occasional projects if used with proper technique, though durability remains a consistent frustration.

Polycarbonate light diffuser cutter

Would Recommend

I needed to replace a polycarbonate fluorescent light diffuser. I had to trim a larger one to fit the broken one. this knife worked very well and getting the job done. I had to take #MIN consecutive scores before the polycarbonate would snap off, but it worked and I am happy.

Read the Instructions

Would Recommend

It was my first time cutting these types of panels and this knife made it easy. Be sure to score the panels several times before attempting to snap. the excess off. It helps to clamp the panels down securely to keep from shifting while using the knife.

Perfect Knife for Cutting Plexiglass

Would Recommend

Small enough to control very easily. I used it to cut a sheet of plexiglass and it worked beautifully.

The main thing to remember is to take your time.

Would Recommend

This is a tool I wish I had had before I started my DIY project, which involved precise cutting of a few sheets of plexi. I watched some videos of folks snap-cutting their plexi with utility knives. Yes, that's possible with a lot of effort, but this little tool works 10X better. As long as you have a flat surface and can measure, this tool will help you produce a clean, accurate cut.
