"Stropping" A Single Edge Razor Blade?

I go through a LOT of single edge razor blades cutting launch lugs to size for kits.

Years back I did some leather work and remembered "stropping" the cutting tools.

Stropping a blade polishes the blade and can knock off some of the worn rough blade edge.

Ideally, stropping is done on the rougher, suede side of leather. A polishing compound is usually rubbed into the leather before polishing.

It seems a razor blade only cut clean through four launch lug cuts! 

I was cutting on a scrap piece of cardboard.

I tried stropping the blade on the cardboard. It helped re-establish the blade edge and let me make more cuts!

On the left, the blade is set down at a shallow angle and drawn to the left side.

Turn over the blade and draw it to the right. 

While the results might not be as good as a leather stropped blade, it did work and extended the usable life of the blade.
