Open Comb vs Closed Comb Safety Razor: Which to Start With

If you are new to wet shaving, start with a closed comb safety razor. The solid or scalloped bar under the blade flattens the skin just ahead of the edge, which makes it more forgiving while you learn the angle and pressure. An open comb razor, with teeth instead of a bar, lets more lather and longer stubble reach the blade, so it suits men with coarse, dense beards or who shave every few days. But the comb is only part of the story. How far the blade sticks out, and the gap between blade and guard, decide how gentle or aggressive a razor really is.

What “comb” actually means

On a double-edge safety razor, the blade sits clamped between a top cap and a base plate. Along the edge of the base plate, just below the blade, is the guard. That guard comes in two broad forms.

• Closed comb (often called a safety bar): a continuous strip of metal, sometimes smooth, sometimes with shallow scallops or grooves. It presses the skin flat and taut immediately before the blade passes.
• Open comb: a row of teeth, like a short comb. The teeth guide hairs towards the blade and leave gaps through which lather and stubble flow.

Both are genuine safety razors. Neither is a cut-throat. The difference is how much of the face meets the blade, and how easily longer hair is lifted into it.

How they feel in use

Closed comb

The bar smooths the skin and limits how much of it the blade can catch. In practice that means fewer nicks around the jaw and upper lip, a bit less irritation on the neck, and a shave that feels calmer, especially in the first few weeks. The trade-off is that very long stubble can bunch against the bar and clog the head, so you rinse more often.

Open comb

The teeth let hair pass straight to the blade without folding over, and lather does not pile up in front of the edge. On a two- or three-day beard, that can mean fewer passes and less tugging. Many open comb designs also expose more of the blade, so they cut more efficiently but punish a poor angle or too much pressure.

The detail that matters more than the comb

Two razors with the same comb type can feel completely different. What decides how “aggressive” a razor is:

• Blade exposure: how far the edge sits above the line between the cap and the guard. More exposure means a closer, more efficient shave, and more chance of a cut.
• Blade gap: the space between the edge and the guard. A wider gap lets more skin bulge towards the blade.
• Weight and handle length: a heavier razor does more of the work, so you push less.
• The blade itself: brands vary noticeably in sharpness and smoothness.

So a mild open comb can be gentler than an aggressive closed comb. When you read reviews or product descriptions, look for words like “mild”, “medium” and “aggressive” rather than relying on comb type alone.

Side by side

	Closed comb	Open comb
Typical feel	Mild to medium, forgiving	Medium to aggressive, efficient
Best stubble length	Daily or every other day	Two to four days, or dense growth
Learning curve	Gentler; mistakes cost less	Steeper; angle and pressure must be right
Sensitive skin	Usually the better choice	Possible with a mild design and care
Rinsing	Clogs more with long stubble	Rinses through easily
Who it suits	Most beginners, most faces	Coarse, thick beards; experienced shavers

Which to start with: a quick checklist

Choose a closed comb if any of these apply:

• You have never used a safety razor.
• You get razor burn, bumps or ingrown hairs.
• You plan to shave daily or most days.
• Your beard is average or fine.

Consider an open comb if:

• You have shaved with a safety razor for a few months and your technique is consistent.
• Your beard is very coarse or dense.
• You usually shave every two to four days.

Many men end up owning one of each: a closed comb for daily maintenance and an open comb for the weekend shave. That is a second purchase, not a first one. For the full list of what you need on day one, see our wet shaving starter kit.

Technique is the same either way

1. Prepare the beard. Shave after a warm shower, or hold a warm, damp flannel on your face for a minute. Soft hair cuts more cleanly.
2. Use a proper lather. A cream or soap built with a brush gives more cushion than foam from a can.
3. Find the angle. Rest the top cap on your cheek with the handle pointing out, then lower the handle until the blade just touches the skin. That is roughly 30 degrees.
4. No pressure. Let the weight of the razor do the work. If you are pressing, something else is wrong.
5. Go with the grain first. Re-lather and go across the grain on a second pass only if you need to. Against the grain is optional, and best skipped while learning.
6. Rinse cold and finish gently. A splash of cool water, pat dry, then a balm.

Our step-by-step guide on how to use a safety razor goes further into passes and tricky areas. If ingrown hairs are a regular problem whatever you use, the NHS guidance on ingrown hairs is worth reading, and if skin problems persist, check with your GP or pharmacist.

What a barber’s shave can teach you

Barbers use a straight razor with replaceable blades rather than a safety razor, but the principles carry across: preparation, a slick lather, light hands and the right direction for each patch of growth. A hot towel shave at Highgate Cuts takes 20 to 30 minutes and starts, like every visit, with an assessment of your skin and growth pattern. Ask the barber to show you which way your beard grows on the neck, which is where most home shavers go wrong. It is the easiest way to map your face before you buy a razor.

Questions we get asked

Is an open comb razor more dangerous?

Not inherently, but many open comb designs expose more blade, so a poor angle or heavy hand is punished more. A mild open comb in careful hands is perfectly safe.

Can I use the same blades in both?

Yes. Standard double-edge blades fit both types. Trying a few brands is worthwhile, as the blade affects the feel as much as the head.

Which is easier to clean?

Open comb heads rinse through more easily. Closed comb heads need a little more rinsing after longer stubble.

Can a barber recommend which one suits my beard?

Yes. During the assessment at the start of any visit to our Archway Road barbers, just ask; your growth pattern and skin tell us a lot.
