Don't want to see this thread fade away! I am sure there are lots of good ideas still out there. Will offer up a super-low-tech tool for something that comes up all the time - cutting of floppy sheet materials like plywood and particle board. See photos. Two long boards, whatever you have, two short boards, whatever you have, screwed together to make a parallelogram. It collapses together to be stored in a corner when you don't need it. Screws need to be driven about 1/2" down to be out of the way of the blade. Add a third short board, movable, to support wherever you are making the cut. No more binding etc. Works good on any sheet material, especially odd shapes. Takes about 2 minutes to make using scrap you were going to throw away anyway.
