This acrylic cutting knife can be used to cut acrylic sheets, including acrylic mirrors.
It is advised that you use a straight edge to keep your cuts consistent.
Be sure to cut all the way to the edge of your sheet of acrylic, otherwise you risk having an uneven break on whatever section is not fully cut into.
When you've cut across the acrylic between 4 and 8 times, you can bend the acrylic sheet to snap it along the line you've cut. Or if you've cut it enough times, you may be able to cut all the way through without the need to bend it and snap it. Please note that this is not a foolproof process and it is possible to damage whatever you are cutting. If you are cutting a large enough piece off, it wouldn't hurt to practice cutting a smaller piece off first to get a feel for how it works.
This has a sharp edge that can easily cut you or others so please use with care and keep out of reach of children or animals.
