So did I hit on something new, or am I the thousandth nimrod to "think of it"?
Cutting out parts from a sheet in an old Sterling kit which, and I know this will surprise many, wasn't die cut all that well. It suddenly hit on me that the die cut in from one side, and if I took a block and sanded the backside of the sheet it might help release the parts. It works! A sanding block with 80 grit adhesive paper cuts quickly and definitely helped parts come out of that sheet.
