Best Safety Razor: Closed Comb, Open Comb and Adjustable Designs Explained
Safety razors use a single, double-edged blade clamped in a metal head. They have become popular again with people who want less plastic waste, cheaper replacement blades and a shave that some find kinder to bump-prone skin than multi-blade cartridges. The catch is that the razor and your technique both matter much more than with a pivoting cartridge.
For most people, and especially beginners, the best safety razor is a mild to medium closed comb razor with a solid, well-finished stainless steel or plated brass head, a textured handle of around ten centimetres and a secure three-piece or twist-to-open design. A closed comb, or safety bar, guides shaving cream and skin smoothly and reduces nicks. Open comb and adjustable razors cut more efficiently on thick, long stubble but are less forgiving. Pair the razor with good blades, change them often, and shave with light pressure at a shallow angle. Avoid rough, poorly finished heads, loose blade alignment and very aggressive razors when you are starting out.
In short: start mild with a closed comb, let the weight of the razor do the work, and replace blades regularly.
The American Academy of Dermatology advises shaving in the direction of hair growth, rinsing the blade after each swipe and changing blades after about five to seven shaves to reduce irritation, all of which apply fully to safety razors.
This buyer’s guide compares safety razor designs, explains aggressiveness, handles and blades, lists what to avoid and shows how to shave, clean and store a safety razor.

What to Know First
- Closed comb razors are the gentlest and best for beginners.
- Open comb and adjustable razors suit thick stubble and experienced shavers.
- The blade matters as much as the razor; try a few to find one you like.
- Use almost no pressure and a shallow angle.
- Shave with the grain first; skip against-the-grain passes on sensitive skin.
- Change blades every few shaves and dispose of them safely.
- Dry and store the razor away from steam to prevent rust and bacteria.
Safety Razor Designs Compared
Safety razors differ mainly in how the head guides the skin and how the blade is loaded. These two factors decide how smooth, efficient and forgiving the shave feels.
| Design | What it means | Feel | Best for |
|---|---|---|---|
| Closed comb (safety bar) | A solid or scalloped bar sits below the blade edge | Mild to medium, smooth and forgiving | Beginners, sensitive skin, daily shavers |
| Open comb | Teeth instead of a bar channel lather and hair to the blade | More efficient, less forgiving | Thick or several days of stubble |
| Adjustable | A dial changes the blade gap | Mild to aggressive in one razor | Experienced shavers who want flexibility |
| Slant bar | The blade is twisted across the head | Slicing, efficient cut | Coarse beards, experienced users |
If you have never used a safety razor, a closed comb head with a mild to medium blade exposure is the safest place to begin. Once your technique is consistent, you can decide whether you want something more efficient. Many experienced shavers still prefer a mild closed comb for daily use, because a gentle razor used every day tends to be more comfortable than an aggressive one used on long stubble, and it is easier on the neck, where skin is thinner and hair often grows in several directions.
Three-Piece, Two-Piece or Twist-to-Open?
How a razor holds the blade affects convenience and durability more than shave quality.
| Loading style | How it works | Pros | Cons |
|---|---|---|---|
| Three-piece | Handle, base plate and top cap screw together | Simple, sturdy, easy to clean thoroughly | Takes a moment longer to change blades |
| Two-piece | Top cap with a threaded post screws into the handle | Fewer loose parts | Slightly more fiddly to clean |
| Twist-to-open (butterfly) | A knob opens doors on the head to drop the blade in | Quick, convenient blade changes | More moving parts that can loosen or misalign over time |
A well-made three-piece razor is often the most durable choice, because there is no mechanism to wear out. Twist-to-open designs are convenient, but check that the doors close evenly so the blade sits straight. Whatever the style, the threads should turn smoothly and the parts should fit together without wobbling, because a loose head changes the blade angle during the shave.
Features to Look For
Beyond the head design, these practical details help a razor feel safe and comfortable.
- Material: stainless steel resists corrosion and lasts; chrome-plated brass is heavy and durable; cheap plated zinc alloy can pit or flake if the plating wears.
- Finish: smooth edges and even plating on the head and cap, with no sharp burrs.
- Blade alignment: the blade edges should sit evenly on both sides once tightened.
- Handle length and grip: around ten centimetres suits most hands; knurling or texture helps when wet.
- Weight: a moderately heavy razor lets the weight do the work so you do not press.
- Balance: a head-heavy or neutral balance feels controlled on the jaw and neck.
Blades vary widely in sharpness and smoothness, and the same blade can feel very different in two razors. Many shavers buy a small sampler pack of blades to find one that suits their skin and razor before buying in bulk.
What to Avoid
Some razors and habits make safety razor shaving more painful than it needs to be.
- Very aggressive open comb, slant or high-setting adjustable razors as a first razor.
- Rough casting marks, sharp edges or uneven plating on the head.
- Razors where the blade sits crooked or loose after tightening.
- Pressing down as you would with a cartridge razor, which causes nicks and burn.
- Using the same blade for weeks, which pulls hair and irritates skin.
- Multiple passes against the grain on sensitive or bump-prone skin.
Safety razors are not ideal for everyone. If you have very curly hair and frequent bumps, even a careful single-blade shave may be too close. Our comparison of facial razors vs normal razors explains the differences between blade types and when a gentler tool makes more sense.
Choosing Blades and Lather for a Safety Razor
Double-edge blades fit almost every standard safety razor, so you are not locked into one maker. That freedom is useful, because blades differ in sharpness, coating and smoothness, and the right one depends on your beard and skin.
- Very sharp blades cut coarse hair easily but can feel harsh on thin or sensitive skin.
- Smoother, slightly less sharp blades are often more comfortable for fine hair and daily shaving.
- Coated blades glide more easily for the first few shaves, then behave like uncoated ones.
- A good lather matters as much as the blade: it should be slick and cushioning, not thin or airy.
- Glycerin-rich shaving soaps and creams tend to give more glide than canned foam.
- Fragrance-free shaving creams are a sensible choice if your skin reacts easily.
Change only one thing at a time, whether it is the blade, the razor or the shaving cream. That way, if your skin reacts or the shave improves, you know what made the difference. Many shavers settle on one blade and one lather they trust and stop experimenting once their skin is consistently calm.
How to Shave With a Safety Razor
The technique is different from a cartridge razor. Go slowly and focus on angle and pressure rather than speed.
Prepare the skin and hair
Shave after a warm shower or wash your face with warm water to soften the hair.
Apply lather
Use a shaving cream, soap or gel and work it into the beard for a minute.
Find the angle
Place the handle flat against your cheek, then lower it until the blade just touches, about 30 degrees.
Use short, light strokes
Let the weight of the razor cut; do not press down.
Shave with the grain first
Follow the direction of hair growth and rinse the razor after each few strokes.
Re-lather for a second pass
If needed, re-lather and shave across the grain, not against it, on sensitive skin.
Rinse and soothe
Rinse with cool water, pat dry and apply a fragrance-free moisturiser or balm.
Stretch the skin gently with your free hand on tricky areas such as the jawline and under the chin. A flat surface helps the blade glide and cuts down on nicks.
Cleaning, Storage and Blade Disposal
A safety razor is easy to keep clean because it comes apart completely. Good care keeps it hygienic and stops the finish from corroding.
- Rinse the head under hot water after each shave to clear soap and hair.
- Once a week, take the razor apart and clean the parts with warm soapy water and an old toothbrush.
- Dry every part with a towel and leave it to air-dry fully.
- Store the razor out of the shower, in a dry, ventilated spot.
- Change the blade every few shaves, or sooner if it tugs.
- Put used blades in a closed metal blade bank or sturdy tin, not loose in the bin.
The American Academy of Dermatology guide on how to shave recommends storing your razor in a dry area and letting it dry completely between shaves to prevent bacteria from growing.
Safety Razors, Razor Burn and Bumps
Many people switch to a single blade hoping for fewer razor bumps. Some find it helps, because a single blade cuts hair at skin level rather than lifting and cutting below it. Others find no difference, because technique and hair type matter more than the number of blades.
If you get small, itchy spots along the jaw after shaving, they may be ingrown hairs, irritated follicles or breakouts. Our guide on tiny pimples on the jawline helps you tell them apart. Leaving a little stubble, shaving with the grain only and shaving less often all reduce the risk.
Do not shave over raised moles, open spots, cold sores or infected bumps. Keep blades away from children, never share a razor, and see a doctor if a cut keeps bleeding or a bump becomes painful, hot or filled with pus.
Dos and Don’ts
Good Habits
- Start with a mild closed comb razor
- Use a rich lather
- Keep the angle shallow and the pressure light
- Change blades every few shaves
- Dry and store the razor away from steam
Common Mistakes
- Press the razor into your skin
- Shave against the grain on sensitive skin
- Use a dull or rusty blade
- Throw loose blades in the bin
- Share your razor with anyone
Most people find the first two or three weeks the hardest, and nicks become rare once the angle and pressure feel natural. If you are also weighing up other hair removal methods, our guide on waxing vs shaving facial hair compares the options.
Honest Limits
A safety razor will not magically eliminate razor burn or bumps. It can give a close, comfortable shave for many people, but only with careful technique, and there is a learning curve with a real chance of nicks at first.
Claims that one razor is universally the best ignore how different faces, beards and skin are. Aggressiveness, weight and blade choice are personal, and the best combination is usually found by trying a mild razor and a few blades. The long-term savings on replacement blades are real, but the environmental benefit depends on recycling or safely disposing of the used blades.
When to See a Dermatologist
- Razor bumps or ingrown hairs keep returning despite good technique.
- Bumps leave dark marks, scars or hard lumps.
- Shaving causes a rash that lasts for days.
- A spot or mole in the shaving area changes, bleeds or does not heal.
