How Often to Change Safety Razor Blade?

A safety razor is a great choice for any man, thanks to the guard beneath the blade edge that helps prevent major gashes while shaving.

It is considered to be one of the best traditional shaving tools that provide a much closer shave. The sharper blade delivers a smooth shave and helps you avoid razor burns, nicks, cuts, and skin irritation. 

It is indeed an amazing shaving tool. But, you have most likely wondered how long does a safety razor blade last and how often to change safety razor blade.

You have probably tried to use a single razor multiple times until it started tugging on your skin, causing nicks and cuts. This is bad and can easily expose your skin to bacteria and irritation.

You can avoid such problems by knowing when to change your safety razor blade.

Why Do Safety Razor Blades Need Changing?

Safety Razor Blade

A safety razor is an extremely durable shaving tool that you can use for decades. But the same cannot be said of the safety razor blades.

The blades are designed for short-term use and you will have to dispose of them after a certain number of shaves. The sharp edges of the blades usually deteriorate with every pass and they eventually become dull.

How Long Do Safety Razor Blades Last?

A high-quality safety razor blade should last about 5 to 10 shaves, depending on your shaving routine.

Supposedly, one blade may be enough for one week’s shaving. This means you will need roughly 4 safety razor blades a month, which sums up to 48 safety razor blades a year.

However, these figures could change if you consider your frequency of shaving, blade quality, type of hair, shaving technique, and blade care.

What Factors Affect the Longevity of Safety Razor Blades?

The longevity of safety razor blades can be affected by a number of factors, which include:

Type of Hair

Is your facial or body hair dark, thick, and coarse or is it light, thin, and fine?

If you happen to have coarse, thick hair, then you should expect your safety razor blades to dull much quicker. This means you will get fewer shaves out of them.

Someone with coarse stubble would probably use two blades in a week, each blade would last about 3 to 4 shaves. But you should be able to get enough shaves to last you a week if you have a soft stubble.

Medium Beard
With medium beard, one safety razor blade will last approximately three to four shaves per week. So, you will need about two blades per week. (Source: menshairstylestoday.com)
Soft Stubble Beard
A soft beard is more like a five o’clock shadow, which doesn’t need too much work done. A single safety razor blade will last about six shaves, which means you can work with one blade per week.

Blade Quality

We cannot stress enough on this point. But if you buy cheap quality safety razor blades, you will most certainly get fewer shaves and you may have to change the blades more frequently.

Here are the key factors that determine the quality of a blade:

  • Material: You need to choose a blade made of high-quality material that is highly resistant to corrosion and has superior edge retention like platinum stainless steel or Swiss steel.
  • Coating: Blades coated with chromium, platinum, or tungsten improve blade quality and longevity. The coating reduces friction to provide a smoother, closer shave and no irritation

Surface Area Covered

The area that the blade covers when you are shaving will affect the longevity of the blade.

You will most certainly get more shaves when you use a safety razor blade on a beard. But you may get only one shave when you use it on your head or legs.

The larger the surface area covered the more blades you will need to change.

Shaving Routine

Your shaving routine can increase or reduce the number of shaves you can get from a safety razor blade.

You don’t want to use your blade on dry skin that is full of skin dead cells.

What you want to do is exfoliate your skin to get rid of dead skin cells, apply a rich shaving lather (made of high-quality shaving soap or cream), and shave with the grain to reduce abuse on the blade’s edge.

Shaving Technique

There are two types of techniques that are usually used when shaving with a safety razor, single-pass, and three-pass techniques.

The three-pass technique is the most effective but it tends to dull the blade pretty fast as compared to the single-pass.

Frequency

How frequently you shave your facial hair also matters.

If you have coarse or medium stubble and shave four to seven times a week, then you will need two safety blade changes per week.

One blade is enough for those shaving their coarse or medium stubble one to three times a week.

But there is no need to use more than one safety razor blade in a week if you have a soft stubble.   

Blade Maintenance and Storage

Safety razor blades are typically made of stainless steel, which is known to have reliable corrosion resistance. But, the corrosion resistance of the blade material will not hold forever.

The water, salt from your skin, and shaving product residue could easily corrode the edges and render the blade useless.

You need to clean and properly dry the blade after every shave to prolong its use.

Here are a few things you can do to extend the life of your safety razor blade:

  • Step1: Remove your razor blade from the safety razor.
  • Step 2: Clean the razor blade with running water to get rid of shaving cream and hair.
  • Step 3: Pat the safety razor blade on a hand towel to dry.
  • Step 4: Dip the razor blade in rubbing alcohol to sanitize and evaporate any water droplets.
  • Step 5: Store the razor blade in a dry place.

Pro Tip: Don’t you ever store your safety razor blades or the safety razor in your washroom. This room has high levels of humidity, which could easily corrode the blades and the safety razor. Instead, store them in a linen closet.

How Do You Know A Safety Razor Blade Need To Be Changed?

A safety razor blade should glide smoothly when shaving. You should change it if:

  • Your safety razor blade pulls or snags, then it is getting dull and needs to be replaced. Dull safety razor blades can cause razor burns, cuts, and nicks.
  • You see any signs of rusting, it can irritate your skin.
  • Your shave becomes less effective, it can’t shave close to the root anymore and your hair quickly grows back.

Generally, you should change your safety razor blade once every three to six days, especially if you are shaving consecutively.

Conclusion

In short, you need to change your blade after every 3 to 4 shaves if you are dealing with coarse, thick hair and after every 7 shaves if you are dealing with fine, thin hair.

But your blade changing frequency could change with other factors like your hair type, your shaving routine, frequency, and technique, the quality of the blades, and how you care for the blade after every use.
