To stabilize the blade, the same method could be incorporated on a quality "Chopper" as that used on a printer's paper cutter - the blade is laminated between two sheets of steel that travel with the blade in the cutting step and also act as a 'press' that holds in place whatever is being cut. Once these steel sheets contact whatever is being cut, they stop their descent, but the blade (still prevented from flexing by the steel sheets) continues down to make the cut.

The single edge razor blade should also be stabilized somehow also to prevent it from flexing.
