Are Safety Razors Actually Dangerous?
No. The clue's in the name — they were invented to be safer than straight razors. They've been around for over 150 years.
The irony is that cartridge razors cause more problems than they prevent:
Cartridge razors
- Multiple dull blades drag and pull
- Clog with debris — bacteria magnet
- Need pressure to cut, causing irritation
- Multi-blade lift-and-cut creates ingrowns
Safety razors
- One sharp blade cuts clean
- Easy to rinse completely
- Blade weight does the work — light pressure
- Single pass means fewer ingrowns
How to Shave with a Safety Razor
Direction of shave
You can shave in any direction. Most people do two passes:
- With the grain — removes the bulk. Always start here.
- Against the grain — gets it smooth. Optional, based on preference.
Four fundamentals
New to lathering? Our shaving soap lathering guide covers technique, bowl options, and common mistakes.
Your first shave: step by step
- Prep your skin. Shower first, or hold a hot towel on your face for a minute. Warm water softens hair and opens pores — this makes everything easier.
- Load the blade. Unscrew or twist open your razor, place a fresh blade on the base plate (centre it on the posts), then reassemble. Don't overtighten.
- Build your lather. Wet your shaving soap and work your brush in circles until you get a thick, creamy lather. A shaving bowl helps, but face-lathering works too.
- First pass — with the grain. Apply lather, then shave in the direction your hair grows. Short strokes, light pressure, 30° angle. Rinse the blade every few strokes.
- Re-lather and second pass. Apply fresh lather. This time go across the grain (sideways) for a closer result. Against the grain is optional — try it once you're comfortable.
- Rinse with cold water. Closes pores and calms the skin. Pat dry — don't rub.
- Aftercare. Alum block or aftershave balm if you want it. Rinse your razor, shake dry, and store it open on a razor stand.
The first few shaves will feel different from a cartridge. Give it 3-4 goes before you judge it. Most people never go back.
What It Actually Costs
Cartridge razors
over 10 years
$8–12 per cartridge, replaced every 1–2 weeks
Safety razors
over 10 years
$0.10–0.50 per blade, razor lasts a lifetime
Blades are cheap because manufacturers compete on quality, not marketing. You'll also find the variety means you can match blade sharpness to your skin and hair type.
Environmental Impact
Around 2 billion plastic razors are thrown away each year. Mixed materials make them impossible to recycle, and the plastic takes 400+ years to decompose.
Safety razor blades are 100% recyclable steel. The handle lasts a lifetime. Blades come wrapped in paper. It's one of the simplest sustainability switches you can make.
Care & Storage
After every shave
- Rinse thoroughly with hot water
- Shake off excess — don't wipe the blade
- Open the razor to air dry
- Store on a Razor Rest, blade up
Don't store it wet or leave it assembled in a humid bathroom. That's how you get rust and dull blades.
Low-profile stand that keeps your razor elevated and dry. The Pro version ($25) adds a weighted base and built-in blade storage. Fits any counter.

Disposing of blades
Never throw loose blades in the bin or recycling. Use a blade bank — it holds hundreds safely.

Understanding Double Edge Razor Blades
All double edge blades fit all double edge razors — they're a universal size. The difference is in sharpness, coating, and how they feel against your skin. Finding the right blade matters as much as finding the right razor.
Sharpness spectrum
Blades range from mild to aggressive. Where you land depends on your hair type and skin sensitivity:
How often to change blades
Every 4-6 shaves for most people. You'll feel it — the blade tugs instead of cutting. With blades costing $0.10-0.50 each, there's no reason to push a dull one.
Try a sample pack
Don't buy 100 of one brand before you've tried a few. A sample pack with 5-6 different brands lets you find your match without committing.
Assorted brands — find the blade that suits your skin and hair type.

Two designs, both excellent. Your call.
Not sure? Start with the butterfly. It's forgiving, convenient, and you'll learn technique without fiddling with parts. Most serious wet shavers end up owning both eventually.
Want everything in one box?
The Complete Kit ($249) has it all — razor, brush, bowl, soap, and Wave XL stand. The Essentials Kit ($99) covers brush, Wave stand, and soap if you already have a razor. Just want the razor gear? The DE Safety Razor Set ($99) gets you a butterfly razor, Razor Rest Pro, blades, and a travel case.
Frequently Asked Questions
Can women use safety razors?
Absolutely. Safety razors work on any body hair — legs, underarms, bikini line. The technique is the same: light pressure, 30° angle, with the grain first. Many women switch because safety razors cause less irritation and ingrown hairs than multi-blade cartridges. Our butterfly razor is a good starting point.
Do safety razors cause less irritation?
Generally yes. A single sharp blade cuts hair cleanly without the lift-and-cut action of multi-blade cartridges, which is the main cause of razor bumps and ingrown hairs. If you have sensitive skin or deal with irritation, a safety razor with a mild blade (like Derby or Shark) is worth trying.
How long does a safety razor last?
The razor itself lasts a lifetime with basic care. It's solid metal — there's nothing to wear out. You just replace the blade every 4-6 shaves. The ongoing cost is essentially just blades at $0.10-0.50 each.
Is a safety razor good for beginners?
Yes — with a small learning curve. The first 3-4 shaves feel different from a cartridge because you're controlling the angle yourself. Start with a butterfly razor (easier blade loading), a mild blade, and take your time. Most people have it down within a week.
What do I need to start wet shaving?
A safety razor, blades, a shaving brush, and a good soap. That's the essentials. A shaving bowl and a Razor Rest Pro (with built-in blade storage) are nice additions but not critical. For the full setup in one box, the Complete Kit ($249) includes razor, brush, bowl, soap, and stand. If you just want the razor gear, the DE Safety Razor Set ($99) comes with a butterfly razor, Razor Rest Pro, blades, and a travel case.
Can I take a safety razor on a plane?
The razor handle is fine in carry-on. Blades must go in checked luggage. Pack a few blades in a paper sleeve inside your checked bag, or buy blades at your destination — they're available worldwide.
Butterfly or three-piece — which should I get?
Butterfly (twist-to-open) is easier to load and great for travel. Three-piece gives you more control over blade gap and aggression. Beginners: start butterfly. Enthusiasts who want to tinker: three-piece. There's no wrong answer.
