Single Blade Shaving: What It Actually Is, and Who It Suits

"Single blade" gets used to mean three different tools, and most guides never say which one they're talking about. So before anything else: here's what the phrase actually covers, what each one is like to use, and who each suits. We sell safety razors and blades — we buy them in, we don't make them — so the razor isn't the part we're precious about. The soap and the brush are. That's relevant, and it comes up later.

The Short Answer

A single blade razor cuts each hair once, at skin level, with one edge. A cartridge razor stacks three to five blades so each stroke cuts the same hair several times, and the first blades pull the hair slightly proud of the skin before the later ones cut it. That's the whole difference, and everything else follows from it — less irritation, fewer ingrown hairs, blades that cost cents, and a technique you have to actually learn.

If you get razor burn, bumps or ingrowns from a cartridge razor, a single blade is the single biggest change you can make. If your cartridge razor has never bothered you, it's a slower, cheaper, more deliberate shave rather than a fix for anything.

"Single Blade" Covers Three Different Tools

This is where nearly every guide on this subject goes vague. There are three distinct things sold as single blade razors, and they are not interchangeable.

1. The double edge (DE) safety razor

The classic. A metal head clamps a thin rectangular blade with a cutting edge on both long sides, and a guard bar sits below the edge to control how much steel meets your skin. It's a single blade razor — one blade, one cut per stroke — even though the blade itself has two usable edges. You flip it or rotate the handle to use the other side.

This is what most people mean by single blade shaving, and it's what we sell. It suits faces, heads, legs, underarms and everything else. Blades cost 10 to 40 cents each.

2. The single edge (SE) razor

Same idea, different blade format: a heavier, thicker blade with one cutting edge, held in a razor built specifically for it. Injector razors and the modern American single-edge razors (the ones you'll see at $100 and up) live here. They're rigid, they don't flex in the head the way a DE blade does, and people who like them tend to like them a lot.

The catch in Australia is supply. DE blades are a global open standard made by dozens of manufacturers; SE formats are narrower, often proprietary to one brand, and cost several times more per blade. If you want one blade, one edge and no thinking, a DE razor gets you there cheaper and with more blade choice. We don't stock SE-specific razors — that's not a knock on them, we just haven't found one worth putting our name next to at a price that makes sense here.

3. The shavette (and the straight razor)

A folding handle that holds a disposable blade — usually a DE blade snapped in half, sometimes a purpose-made SE blade. No guard bar at all. The edge is fully exposed and the angle is entirely up to you. It's what barbers use for neck lines and detail work, because it's disposable and doesn't need honing.

It gives the closest shave of the three and it is unforgiving. Not a first razor. If you're curious, we wrote about it properly: what a shavette is and how it compares to a safety razor.

Which one should you start with?

A double edge safety razor. It's the format with the guard bar, the cheapest blades, the widest blade choice, and the shortest learning curve of the three. If you later want the extra closeness of an exposed edge, you'll have the technique for it by then.

Is It Better to Shave With One Blade or More?

Depends what you're optimising for, and we'd rather say that than pretend it's clear-cut.

One blade wins on skin. A cartridge razor drags three to five edges across the same strip of skin in one stroke. The leading blades tug the hair up slightly before the trailing blades cut it, which means the hair is severed below the surface and then retracts. That's a great way to get a shave that lasts an extra couple of hours, and it's also exactly the mechanism behind ingrown hairs and the bumps that follow. One blade cuts at the surface and leaves it there.

One blade wins on cost. DE blades run 10 to 40 cents. Cartridge refills run $4 to $8. The handle is a one-off that lasts decades. We've done the full year-by-year sums in our safety razor vs cartridge comparison rather than repeat them here.

Multi-blade wins on speed and forgiveness. A cartridge head pivots, the guard does the angle work for you, and you can shave badly with one and get away with it. Two minutes, no lather, no thought. That's a real advantage on a Tuesday morning and pretending otherwise helps nobody.

Multi-blade wins on travel. Loose DE blades go in checked luggage. Cartridges go in your carry-on. Airline rule, not ours.

So: better for your skin and your wallet, worse for speed and convenience. If your skin has never complained, the honest answer is that you're not missing much except the money.

Why Do Dermatologists Get Quoted on This?

Because the mechanism above is easy to explain and it lines up with what they see. The standard reasoning goes: fewer blades passing over the same skin means less friction and less micro-trauma, and cutting at skin level rather than below it means fewer hairs curl back into the follicle. For pseudofolliculitis barbae — the medical name for the persistent razor bumps a lot of men with curly or coarse hair get — cutting the hair proud of the skin instead of below it is a standard piece of advice, and a single blade does that where a multi-blade cartridge specifically doesn't.

Two caveats, because this gets overstated online. First, it isn't a universal medical recommendation — plenty of dermatologists will tell someone with no irritation to keep using whatever works. Second, a single blade used with pressure, a blunt blade, or no lather will wreck your skin faster than any cartridge. The razor is a tool, not a treatment. If you have persistent bumps, cysts or infection, that's a GP or dermatologist conversation, not a razor purchase.

If it's ordinary irritation you're chasing off, we've written both sides of it up in detail: what actually causes razor burn and why razor bumps and ingrown hairs happen.

The Downsides Nobody Puts in the Marketing

We sell these things, so take the list as seriously as you like — but it's a real list.

  • There's a learning curve. Three to five shaves before it feels normal. You will probably nick yourself once. It's a weeper on the jawline, not a hospital trip, but it happens and it's better to expect it.
  • It takes longer. Five to ten minutes done properly, against two or three with a cartridge. Some people discover they like that. Some people have kids and a train to catch.
  • Pressure is the enemy and your hands don't know that yet. Every instinct from cartridge shaving — push harder, go over it again — makes a single blade worse. Unlearning it is most of the learning curve.
  • Awkward geography is genuinely harder. Under the nose, around the jaw, the back of the neck, the bikini line. No pivoting head means you move your hand instead. It comes with practice; it is not free.
  • Blades need storing and disposing of properly. Loose used blades in a kitchen bin is how someone gets cut. A blade bank ($20) takes years' worth and never opens; the free DIY options and what councils actually accept are in our guide to disposing of razor blades in Australia.
  • It's not a cure. If your irritation comes from shaving dry, shaving daily on angry skin, or a blade you've used fifteen times, a new razor will not fix it.

How to Actually Use One

The full walkthrough — loading a blade, first shave, what to expect — is in how to shave with a safety razor without cutting yourself. The four things that matter most, in order:

  1. Angle: about 30 degrees. Lay the head flat against your face, then tilt back until the edge just engages. That's your angle. Most beginners hold it far too steep.
  2. Pressure: none. The weight of the razor is the pressure. Your hand's job is to steer it, not to push it. This is the one that fixes most people's first bad shave.
  3. Short strokes, and go with the grain first. Two or three centimetres at a time. Re-lather and do a second pass across the grain if you want it closer. Chasing perfection in one pass is how you get razor burn.
  4. Change the blade before it's blunt. Three to five shaves for most people. A blade that tugs instead of gliding is a blade that's done. Which blade suits you is genuinely personal — the blades guide explains why, and why a sampler is the only honest way to find out.

Single Blade Razors for Women

The same razors. There is no such thing as a women's safety razor in any engineering sense — a longer handle helps for legs and a butterfly head is quicker to rinse between passes, and that's the extent of it. Everything above applies to legs, underarms and bikini line without modification.

The case is arguably stronger, for two reasons. Cartridge refills marketed to women cost more than the identical men's ones, and legs are a much larger surface area, so you burn through them faster — the saving from 40-cent blades is bigger. And the bikini line and underarms are exactly the places where a multi-blade razor's cut-below-the-surface habit turns into ingrown hairs.

Technique notes specific to legs: they're easier than a face because the surface is flatter and there's less contouring. Knees and ankles need short strokes and a slow hand. Go with the grain on the first pass even though it's tempting not to. And use a proper lather rather than shower gel — soap-and-water films break down under the blade, which is where most leg-shaving nicks come from.

More on the switch itself, including the cost side: safety razor vs cartridge razor.

The Part That Matters More Than the Razor

Here's the thing we'd rather be honest about than sell you a razor over.

We buy our razors in. We choose them carefully — two of them, not forty — but we don't make them, and past a certain quality floor one well-made DE razor shaves much like another. What we do make, by hand, in Moss Vale, is the part that decides whether a single-blade shave feels good or feels like sandpaper: the lather.

A single blade has nothing between it and your skin except what you put there. Canned foam is mostly air and propellant — it looks like protection and behaves like nothing. A dense lather off a hard soap does three jobs at once: it holds water against the hair so it softens and cuts cleanly, it puts a real film between steel and skin, and it lets the blade glide instead of drag. That is the whole ballgame with one blade, and it's the step most people skip on their first attempt before deciding single blade shaving isn't for them.

  • Artisan shaving soap — from $29.95, made here in small batches. A hard puck that whips into a dense, slick lather and lasts months, not weeks.
  • A shaving brush — from $69 with the stand included, badger or synthetic, on polymer or solid timber handles. The brush is what lifts the hair off the skin and works water into the soap; your hand can't do either.
  • A lathering bowl — from $35, solid timber or our own matte black polymer, sized so a soap tin drops straight in. Not essential, but it holds heat and gives you more control than a palm does. Bowl vs face lathering if you want to decide first.
  • Shave oil — from $29.95, three plant oils and nothing else. Goes under the lather if your skin is difficult, or shave straight off it.

New to building lather off a puck? Here's the step-by-step. It takes about a minute once you've got it.

What You Need to Start

Three things: a razor, blades, and something to lather with. You can assemble it yourself or take it in one box.

Piece by piece

The artisan shaving soap (from $29.95) and a brush from the brush range (from $69, stand included) are the parts we make. Add a razor from there: the WÖLFE 97 ($59) is a three-piece DE razor with a bit of weight to it and it ships with a blade sampler, and the WÖLFE 75 ($59) is the butterfly version — twist the handle, the head opens, drop a blade in. Lighter, quicker to rinse, easier if you're doing legs. Replacement DE blades start at $10 for a mixed pack. Both razors are chosen and bought in, not made here — we'd rather say so.

In one box

The Shaving Set ($99) is the lathering half done properly — handmade brush, Wave stand and artisan soap. Add a razor to it and you have the lot. The DE Safety Razor Set ($99) goes the other way: razor, Razor Rest Pro stand with blade storage, blades and a travel case.

If you want the whole thing settled in one purchase, the Complete Shaving Kit ($299) is the Grand Wave teak stand, badger brush, timber bowl, safety razor and soap together. Above that the Premium Magic Shaving Kit ($349) suspends the brush from a solid timber arch, and the Luxury Magic Shaving Kit ($499) puts a silvertip badger knot on it and adds a matched 30ml eau de parfum. All of them are here.

Still deciding between the two razors? WÖLFE 97 vs WÖLFE 75 puts them head to head. Or browse the razors and blades if you already know what you're after.

Common Questions

Is it better to shave with a single blade?

For skin, generally yes — one blade cuts the hair at the surface instead of pulling it up and cutting below it, which is the mechanism behind most razor bumps and ingrown hairs. For speed and convenience, no. A cartridge razor is faster and more forgiving. If you get irritation, switch. If you don't, you're switching for the cost and the ritual, which are both real but smaller reasons.

What are the downsides of using a single-blade razor?

A learning curve of three to five shaves, a longer shave (five to ten minutes rather than two), more care needed around the jaw, neck and bikini line where there's no pivoting head, and used blades that need proper disposal. Blades also have to go in checked luggage when you fly. None of it is a dealbreaker; all of it is real.

Why do dermatologists recommend single-blade razors?

The reasoning usually given is that fewer blades passing over the same skin means less friction and less micro-trauma, and that cutting the hair at skin level rather than below the surface means fewer hairs curl back into the follicle. It's advice most often given to people with coarse or curly hair who get persistent razor bumps. It isn't a blanket medical recommendation — and a single blade used with pressure or a blunt blade will irritate skin more than a cartridge, not less.

What's the difference between a single edge razor and a double edge safety razor?

Both cut with one blade per stroke. A double edge razor takes a thin blade with a cutting edge on each long side — the global standard, made by dozens of manufacturers, 10 to 40 cents a blade. A single edge razor takes a thicker, more rigid blade with one edge, usually in a proprietary format, and the blades cost several times more. For most people in Australia the DE razor is the practical choice on blade cost and availability.

Is a single blade razor good for women?

Yes, and it's the same razor. There's no engineering difference between a men's and a women's safety razor — a longer handle and a butterfly head are handy for legs, and that's the extent of it. The savings are usually bigger, because refills marketed to women cost more and legs get through them faster, and the bikini line and underarms are where multi-blade ingrown hairs are worst.

Can I shave my pubic area with a single-blade razor?

Yes, and a lot of people specifically switch for it — it's the area where multi-blade cartridges cause the most ingrown hairs. Go slowly, keep the skin taut with your free hand, use short strokes with the grain, and use a real lather rather than shower gel. Don't press. If the skin is already irritated or broken, leave it a few days.

How long does a single blade last?

Three to five shaves for most people, sometimes seven or eight. You'll know it's done when it starts tugging instead of gliding. At 10 to 40 cents a blade there's no reason to push a dull one — more on blades here.

Do I need a shaving brush and soap, or can I use canned foam?

You can use foam. It just doesn't work very well with one blade — it's mostly air and propellant, so there's very little between the steel and your skin. A hard soap and a brush build a dense lather that holds water against the hair and lets the blade glide. With a single blade this matters more than which razor you bought.

The Bottom Line

Single blade shaving is one blade, one cut, at skin level. It's cheaper to run, easier on skin that objects to cartridges, and it asks for a few minutes and a few shaves of practice in return. The three tools under that name are not the same thing — start with a double edge safety razor, leave the shavette until your hands know what they're doing, and don't pay single-edge prices until you know you want them.

And whichever you land on: the lather is doing more of the work than the razor is. That's the part we make.
