The Bosch 101AO 20 tooth Progressive blade is just the right jig saw blade to cut through hardened acrylic sheets. I just finished building an enclosure around the drivers seat in a Ford E350 passenger bus. We only used one blade to do all the cuts through 1/2 inch sheets. There were a lot of curved cuts and copes to fit the acrylic sheets around the fiberglass bus bulkheads, passenger grab bars and other odd angles. Chucked it up in an old Bosch barrel grip jig saw and these blades provided smooth, straight cuts. No wandering and the cut edges were square. Slow going but problem free.
