Safety Razor vs Disposable
Safety razor wins — one metal handle replaces a lifetime of plastic sticks.
A safety razor is a single metal handle and a removable double-edge blade. A disposable is a sealed plastic cartridge thrown away every two weeks.

The differences
| Safety | Disposable | |
|---|---|---|
| Handle | Brass or stainless steel (lifetime) | Polypropylene (2 weeks) |
| Blade | Steel — recyclable | Bonded plastic + steel cartridge |
| Cost per shave | ~$0.02 | ~$0.50 |
| Plastic per shave | 0g | ~1.8g (amortised) |
| Curbside recyclable | Handle: yes. Blades: scrap metal | Almost never |
Why one wins
The handle is brass or stainless and lasts a lifetime. The blades are pure steel, accepted in any scrap-metal stream, and cost roughly $0.15 each. By contrast, a multi-blade cartridge razor combines plastic, rubber, and bonded metal in a single unit that no recycler will separate.
Annual plastic per person from disposables and cartridges is ~280g. Over a decade, that's ~2.8kg, all of it landfill-bound.
Shave quality with a sharp double-edge blade is widely regarded as superior, with less irritation than multi-blade cartridges.
