Is It Better to Shave with a Single Blade? [2021]

Is It Better to Shave with a Single Blade?

It is actually better to shave with a razor that only has one blade. One blade will tend to irritate/scrape your skin less while still giving you a close shave. It only takes one sharp razor blade to cut hair.

You can use either a single blade disposable razor [BIC Single Blade Disposable] or a safety razor. I prefer using a safety razor like a Edwin Jagger DE89 or Parker 69CR safety razor. These are really nice.

Single Blade Razor Benefits

Less Skin Irritation – the fewer blades in a razor the less your skin gets scraped. It’s plain and simple math. More blades will scrape your skin more with more risk of razor burn or nicks. I’ve used single blade razors, 2 blade, 3 blade and 4 blade razors and I can tell you the 4 blade razors irritate your skin more. Single blade and double blade razors are the least damaging to your skin.

When I use a 4 blade razor, I can tell my skin is scraped more. It feels a little raw afterwards. When I shave with a single blade safety razor, my skin does not feel irritated or scraped at all. It’s especially noticeable on my neck.

Shaving Tip: try to shave with a single pass if possible. The more times you go over an area the more chance of skin irritation.

Easier to Maneuver – single blade disposable razors have a really small head vs a 3 or 4 blade head. The smaller sized razor head makes it really easy to move around and get into hard to get to areas like under the nose, underarms, pubic areas and the back of the neck.

Single blade disposable razors are also smaller and lighter. They are easier to hold and can get into awkward places. The skinny handles make them easy to hold with just your fingers. Just try to shave your underarms or pubic hair with a 4 blade razor. No Way.

No Blade Clogging – single blade razors do not clog or don’t clog as easily as multi-blade razors. My safety razor never clogs unlike the 4 blade disposable razors I have used. These clog easily and are harder to rinse out cleanly. When a razor gets clogged, it won’t cut smoothly and will nick your skin. Clogged razors are dull.

I can shave most of my face with a safety razor without rinsing the blade. It just doesn’t get clogged. I’ve also used BIC single blade disposable razors too. They’re not as sharp as a safety razor but will work well for most people. They don’t clog as easily as multi-blade razors either.

Close Shave – it only takes one sharp blade to cut hair. Believe it or not one blade can cut hair really close. Safety razors and straight razors prove this point everyday. They can give you a really close shave.

The 3, 4 and 5 blade razors are all marketing. They want you to believe more blades is better. But it’s not true. I have tried 3, 4 and 5 blade disposable razors and they do not cut closer or better than 1 or 2 blades. It’s just a waste of money to buy the expensive 5 blade razors. At least for me. I’ve tried them and prefer 1 or 2 blades.

The 5 blade razors are really overkill. You can feel much more drag or scraping with 5 blades. It’s definitely noticeable. 3 blades is the maximum I will ever use. I prefer 1 blade.

I shaved one side of my face with a 4 blade razor [BIC Flex 4] and the other side with a safety razor. I could not tell the difference.

Less Razor Bumps or Ingrown Hairs – I have noticed that shaving with a razor with more blades causes more razor bumps. I think the hair gets cut too close and starts to curl under when it grows back. When I use 4 blade razors on my legs, I get a lot of razor bumps and ingrown hairs. The single blade razors do not cause razor bumps on my legs. Yet they seem to shave close.

Single Blade Razors are Cheaper – Single blade disposable razors are really cheap, like less than a buck. If you use a safety razor then you will save even more money. Good double edge razor blades cost about 10-25 cents a piece. The safety razor itself will cost about $30.

Some of the 4 and 5 blade disposable razors can cost between $2 and $4 a piece and will last about 10 shaves. There is a lot of waste using disposable razors. If you want to be eco-friendly, use a safety razor. It’s cheaper in the long run and less wasteful.

Exfoliation – one blade will exfoliate just as well as 4 blades. The single blade will remove dead skin cells and unclog pores as well as any razor plus reduce irritation.

Single blade razors have been used for hundreds of years and for good reason….they work.
