Razor blade will work...score it a few times to get about half way through and you can snap it like regular glass.

A blade with 70+ teeth ask purpucell on here I think he has one

the best thing to use is a router bit it gives you a perfect cut with a clean egde.

How do you run 1/2in stuff through a router? Does it have to be a special bit? I use a heat wire to cut the thicker stuff then hand finish the edges

 

[electrodude]

you set up a jig or fence to run the router along and you could you could use a flush trim bit

score and snap worked well for me.

the flush trim bit has a bearing to run along your jig (a piece of wood that sits under your acrylic (plexi glass) you clamp them together and clamp them down on a table and pretty much trace the wood out with your router). just make sure that the bearing rolls on the wood and the bit cuts the your acrylic,(check the depthon the router bit). This eliminates the need to hand finish the edges and gives you a perfect clean cut. if you cut a lot of plastic buy a good flush trim bit.

Petersen Bros. Plastics in Chicago sells cutting knives which are much more efficient then using razor blades or utility knives. If you can get the blue handle (thick blade) and yellow handle (narrow blade) and use them in sequence you get the best cut for scoring and snapping acrylic.
