Crown tooth and spiral blades are two of the most common specialized scroll saw blades. Similar to the reverse tooth design, a crown tooth blades cut both on the up and down stroke. Crown tooth blades are a top choice for extra-smooth and chip-free cuts in plastics.
With bi-metal blades you have to watch for build-up though. Pull the saw out and you see the teeth buried/covered in aluminum. Blade speed seems to make a difference. A good jigsaw (my favorite is the Milwaukee with a nice speed control) and you can follow any line, even a straight rip cut. The higher end jig saws have very low vibrations and tend to make very controlable cuts.
