How to keep a disposable razor blade sharp
Disposable razor blades are expensive. Insanely expensive. $3 per cartridge expensive.
Fortunately, I only have to shave twice a week. Still, it annoyed me when I had to go to Costco and lay down over $40 for blades.
I found this video, tried it and have been using the same cartridge for a few months now. Yes, it really works.
Anyone else have any tips?
