I tried looking, but I couldn't find any new ones, and I'm guessing that antique ones won't be useful due to the leather being too old & unmaintained. But, I'll keep looking.
Every time I change blades, I keep thinking of straight razors and stropping them, and wondering why I'm wasting a blade that can perfectly well be sharpened to use again. It seems wasteful. God knows a "dull" razor blade is still incredibly sharp.

Renegade, when I was using double-edged blades - Gillete, Shick - it was common practice to
strop the blade against a bathroom mirror. That realigned the edges, smoothing out the parts that had been realigned/misaligned by the act of shaving. Dunno that might help ya, but it's worth a try. Saved me a great deal of discomfort when I couldn't afford a new blade every day.
