The way I do it is with a ChopperII. You can find it at
www.micromark.com. It uses a single edged razor blade. It make a nice straight cut. It also comes with two angled pieces to do the standard 45, 60, 30 degree cuts.
Me too. It's a great tool. I modified mine slightly to get a deeper cut, and I also use the Tru-Sander by the same mfg. to get really perfect fitting joints.
