As daily tasks go, you might not think much about shaving. A tedious necessity, maybe, but not something that many people devote much time or interest to. But shaving doesn’t have to be a dull affair of an electric shaver mindlessly passed over your face. There’s something special about a shave with a straight razor, which most people only experience occasionally at the barber shop, if at all.

But it needn’t be that way. You can learn the art of shaving with a straight razor and experience both the pleasant feeling of freshly shaved skin and the satisfaction of learning a new skill.

One of the most important factors in getting a good shave, aside from properly preparing your skin and hair, is having a good quality razor. Even the best razor will wear down over time, though, and it will do a bad job if it’s blunt. Save your face by taking care of your razor properly and mastering the art of razor maintenance. We chatted to The Art of Shaving’s Master Barber, Samuel Segev, to learn about how to sharpen a straight razor and to get all the insider tips and tricks on getting the best shave possible.

Why sharpen a straight razor?

“A dull straight razor will pull and tug at the hair and skin,” Segev points out. “Because of this, many people tend to apply too much pressure while shaving and nick themselves.” It’s important to keep your razor as sharp as possible for every use, allowing the blade to do the job without applying a lot of muscle.

Like having the proper espresso machine or a solid pair of needle-nose pliers, you’re going to need the right tools for the job, including starting with a quality straight razor. That said, we recommend using The Art of Shaving Blade Straight Razor as its hollow ground blade delivers a smooth, clean shave that will help you achieve a freshly groomed look.

Stropping the blade

“It is recommended to strop your razor with sharpening strop paste prior to each shave. However, this does not replace honing a straight razor. When your razor begins to pull at the hair and not cut easily that’s when you’ll need to hone your razor.”

That was a lot of vocabulary. Let’s define some terms. 

What’s a strop? A strop (the noun) is a wide leather strap: one side is leather; the other is fabric, with a hook of some sort at each end. To strop (the verb) means to use the strop to sharpen a blade, like this: 

  • Attach one hooked end to a secure surface, hold the other in your less dominant hand. 
  • Hold the blade just above the handle between the forefinger and thumb of your dominant hand. Hold between the cutting blade itself and the handle, allowing for an easy rotating movement. 
  • Pull the strop taut and hold the cutting edge of the blade down and flat against the leather side of the strop, near the bottom, and apply a little pressure. 
  • Draw the blade up the strop, then, without raising the strop into the air, rotate it between your finger and thumb so the opposite side of the blade is now resting on the leather pointing up. Then, draw it down the strop. 
  • Do this about twenty or thirty times. 

The movement actually restructures the blade’s cutting edge, making it sharp for its next use. Think of it as a kinder, gentler version of sharpening your kitchen knives on a stone or grinder. Use the fabric side to wipe away any excess metal bits, soap, etc., that remain on the blade. Be sure not to lift the blade into the air and come back down to the strap, as you are much more likely to cut or nick the strop.

To ensure your technique is safe and barber chair-ready, check out this YouTube video for an in-depth guide to stropping. Now, you may want to consider adding The Art of Shaving Hanging Razor Strop to your grooming kit to maintain your razor’s sharpness for your next shaving session.

Using strop paste

Strop paste includes small bits of grit — in this case, aluminum oxide and diamond particles — suspended in a paste for fine sharpening. 

  • Spread the paste on the leather side of the strop
  • Use the heel of your hand to be sure it’s spread evenly across the surface. 
  • Repeat the stropping process as described above
  • Use the fabric side of the strop to clean the blade
  • Remove the strop paste with a paper towel
  • Strop the blade once more on the clean strop

Honing stone sharpening technique

When buying a new straight razor, it will most likely arrive factory-honed or sharpened. “At The Art of Shaving, we find clients may prefer a sharper edge,” says Segev. “A #4000 and #8000 grit honing stone will bring a normal razor back up to shave ready. An extremely blunt razor may need a coarser stone to begin with, but generally, we recommend asking a professional to hone the razor. Make sure to strop with a leather strop and sharpening strop paste prior to every shave.”

If you’re looking for a sharper shave, or if you’ve been stropping your razor every day but feel like you need a slight touch-up, try this: 

  • Wet the stone
  • Similarly to the stropping motion, hold the blade against the stone and apply slight, gentle pressure.
  • Push the blade, cutting edge side first up the stone
  • Flip the blade over and return
  • Repeat for about five or ten minutes
  • Test by seeing if a hair dropped across the blade cuts easily.
  • If it doesn’t return to your strop and try this next technique

How often should you sharpen a straight razor?

It’s important to care for your straight razor, both for its longevity and so you can enjoy a better shave, but sharpening requires some skill to learn and it can take quite some time. How often you need to do this will depend on factors like your particular hair and skin types, not to mention how often you’re shaving. And obviously if you’re shaving other people as well as yourself then you’ll need to sharpen much more often.

As a rough guide, though, for an average person shaving their face daily then you should be sharpening your razor every few months. Some advise as often as once a month, especially if you have particularly coarse hair, and other say you can get away with sharpening every six months or even every year. But the best way to tell when your razor needs sharpening is to pay attention to how it feels on your skin. If it feels like it’s tugging or yanking at the hair, then it’s time to do some maintenance on your tools.

If you find that the maintenance is getting to be tiresome, or if you don’t want to be caught with a dull razor when you really need a good close shave for a special event like a job interview, then it can be helpful to keep two identical razors which you can switch between. Sharpening both at the same time is less of a hassle than having just one blade you need to sharpen more regularly.

And of course there’s always the option to take your razor to a professional, who can hone it for you. That’s advisable if you’re worried about damaging the blade or if you just don’t have the time to learn the skill of honing for yourself.

Storing the straight razor blade between shaves

Like any good tool, the best way to care for a straight razor is to store it properly between uses. Segev suggests storing your razor in a straight razor display box. Simply searching online will yield numerous beautifully handcrafted boxes that come with protective pads for safeguarding your precious razor from damage, keeping it in pristine condition for future use. Overall, a storage box will go a long way to ensuring it continues to work effectively. But before storing the blade, make sure to carefully wipe it down with a microfiber cloth.

As a quick refresher, remember that shaving is never as simple as it seems. Segev reminds us that if you shave incorrectly, you could leave your face with irritation. His tips for the perfect shave include: 

  • Hold the razor properly: Place your ring finger on the tang of the straight razor. Your index and middle finger should sit on the spine with your thumb placed under the shank. 
  • Hold the blade at approximately 30 degrees. Many men will increase or decrease the angle slightly. 
  • Pull the skin taught and use short choppy strokes to remove the hair.

How The Beard Club Helped Me Grow a Beard
John Jones after beard growth

I was a failure … the facial hair equivalent of a 90-pound weakling. It wasn’t so much that I couldn’t grow a beard; it was more that whatever facial hair I did grow felt like a Velcroed-on Brillo pad: super uncomfortable and leaving my skin itchy and broken out. As Movember and No-Shave November came and went, I made two separate attempts at beard growth … each ending with a sprint into the bathroom when I could stand it no more, trimmer in hand, welcoming back the clean-shaven face I know so well. It wasn’t the first time I’d given up on hirsute happiness. 

When December rolled around, I decided to pay attention to an email I’d gotten for something called The Beard Club, a subscription service for beard care products. The Club’s premise was “helping first-timers as well as seasoned hirsute gentleman to up their grooming game.” I couldn’t resist and threw down the gauntlet. Could they help even me? After all, the site’s tag line is “Don’t Grow it Alone.”

The best-selling colognes for men (because some things are popular for a reason)

The way you smell is the message you send before you even open your mouth or shake a hand. When someone meets you for the first time, your style can give them a great first impression from a distance. But then your cologne will be the storyteller up close. Smelling good is one of the main points of men’s grooming. Soaps, shampoos, lotions, all fragrant and elevating your attractiveness, and ultimately, your memorability.

That is why popular men’s colognes become, well, popular. These are the scents that stand the test of time. The ones that linger on your shirt when you leave, and your girl wears it to bed. The kind that stays around in the office (subtly, not drifting throughout the office because you take a bath in it) after you have gone. And the kind that sparks memories of great dates in the past when she smells it on you before leaving the house. Of course, the best of the best sell like the best of the best. And these are the colognes that sell better than any other year in and year out.
