		lgsilver on Sept 4, 2024 \| parent \| context \| favorite \| on: Shaving is too expensive If you’re supposed to replace modern cartridges every 3-5 shaves, I’ve been doing it wrong. The steel blades in a cartridge easily stay sharp through dozens of shaves. The reason people replace cartridges is because they get clogged with soap and hair. If you rinse them every time, they last significantly longer than single blades.

I don't shave my face, cuz I'm a lady. I do shave my pubes and armpits regularly. I replace the cartridge on my razor like twice a year.

Exactly my thoughts. 3-5 shaves? I use them for tens of shaves. Maybe I'm doing it wrong, but I'm glad I do.

I've been using the same mach 3 for the last 5-6 years, I think.
