In this tutorial, we learn how to scribe break an acrylic sheet. You just need a Stanley knife and a straight edge to do this to any acrylic sheet. First, put some gloves on and safety glasses. From here, level out the area you want to cut on your sheet, then clamp the angle while laying down. Next, use your knife to cut along the edge, going over the same spot several times. Press down hard to ensure it's completely cut. To finish, all you have to do is to bend the excess piece down and it should fall off from the rest right away!
