The thing about shaving with safety razors and $0.10 blades is you order 100 at a time. Just checked my stock and at 2 weeks/blade I'm good for 2+ years before I have to sharpen my straight razor. #lockdown
@ers0 I have an antique German travel safety razor with a nested handle that fits into a small square metal case. Maybe it's due to how the small metal case shows up in X-rays but I've never had a problem traveling with a single blade inside it.
