The best tool to use for cutting plexiglass is a saw. The type of cut an individual desires determines the specific saw recommended for the job.
Circular or radial saws are best for straight line cuts, a scroll saw works best for cutting small curves, and a band saw is best for larger radius curves. Routers can be used to finish the edges of any piece of cut plexiglass. Individuals without access to power tools can use the scribing method, in which a straight line is etched or scored onto the plexiglass and the piece is then broken at the scribed line.
