Disposable and cartridge razors are billions of chunks of mixed plastic-and-metal headed for landfill every year — impossible to recycle and endlessly rebought. A safety razor — the classic metal razor with a single replaceable blade — fixes both problems: it lasts decades, and its blades are cheap, plain steel you can actually recycle. The only catch is a short learning curve. Here's how to shave with one properly.
What a safety razor is
A weighty metal handle and head that holds a single double-edged blade. You replace only the blade (pennies each), not a plastic cartridge — and one razor can last a lifetime. This is one of the standout swaps in our plastic-free bathroom guide.
How to use one (the technique)
The whole trick is let the blade do the work — no pressure:
- Prep the skin. Shave after a warm shower, or soften with warm water; use a shaving soap or oil, not dry.
- Hold at about a 30° angle to the skin — most nicks come from too steep an angle.
- No pressure. Let the weight of the razor glide; pressing is what causes cuts.
- Short, slow strokes, rinsing the blade often.
- Go with the grain first. For a closer shave, re-lather and go across the grain — save against-the-grain for once you're confident.
- Rinse, dry the razor, and stand it to air-dry so the blade lasts longer.
Avoiding nicks and irritation
The first few shaves feel different — expect a small adjustment, not perfection. Keep the angle shallow, never press, don't rush, and replace the blade once it tugs (a dull blade causes more irritation than a sharp one). Within a week or two it becomes second nature.
Recycling the blades
Blades are plain steel and recyclable — but never loose in your bin or kerbside recycling (they're a hazard to handlers). Collect used blades in a blade bank (a small tin, or the slot some razors' boxes include) and, once full, take it to a scrap-metal recycler or a program that accepts them.
Does it save money?
Dramatically. A safety razor costs a bit upfront, but replacement blades are a fraction of the price of cartridges — it pays for itself within months and keeps saving for years, the same buy-it-once maths as most reusables.

Are safety razors hard to use? There's a short learning curve — mostly getting used to a shallow angle and no pressure — but most people are comfortable within a week or two, and the shave is closer than a cartridge once you've got it.
How do you recycle safety razor blades? Collect them in a blade bank (a small metal tin) rather than putting them loose in recycling, which is dangerous for handlers. When full, take it to a scrap-metal recycler or a blade-recycling program.
Do safety razors save money? Yes, significantly. The razor is a one-off cost and blades are pennies each, versus repeatedly buying expensive plastic cartridges — it pays for itself within months.
How often do you change the blade? Every 5–10 shaves as a rough guide, or whenever it starts to tug or feels less smooth. A sharp blade shaves more comfortably and safely than a dull one.
The bottom line
A safety razor turns shaving from an endless stream of plastic waste into a buy-it-once ritual: metal handle for life, cheap steel blades you collect and recycle. Keep the angle shallow, use no pressure, go with the grain first, and give it a couple of weeks. You'll get a closer shave, spend far less, and stop sending cartridges to landfill for good.
