In this blog post, we’ll answer this question and more.

How Often Should I Change My Safety Razor Blade?

The general rule for those who shave daily is to replace your safety razor blades after five to six or even 10 shaves or once a week. This is a good guideline to follow for a smooth and safe shave.

However, the lifespan of a safety razor blade might vary depending on factors such as the type of razor, the frequency of use, and the length and coarseness of your facial hair. The best way to know if your blade needs to be replaced is to look for signs of dullness or tugging.

I’ve personally used each blade at least 25 times.

If your razor isn’t gliding smoothly over your face, it’s time to switch out the blade. It is important to replace the blades after a week of shaving and more if they show signs of rust. To ensure sharpness, razor blades should be replaced regularly as needed.

Follow these tips below for a safe and close-shave experience!

If You Shave Every Other Day, Replace Your Blade Every 5 Shaves

If you shave every other day, you can get away with stretching your blades for a few more days. However, you should still replace the razor blades after five shaves to ensure a smooth and safe shave.

To extend the life of your razor blades, use a shaving brush to lather up your shaving cream or gel and ensure that you rinse the blade off between strokes. This will help remove any excess hair or skin particles that can clog the blade and cause it to become dull prematurely.

Change Blades When Tugging or Roughness Begins

Regarding safety razors, the consensus is that it’s best to change the blade when tugging or roughness begins. This can signify dullness in the blade, which can cause irritation and razor burn. If you feel tugging while shaving, it’s best to replace the blade immediately.

It’s also important to replace your razor blade before it grows too dull. While it’s possible to get a few shaves from one blade, it’s best to switch out blades to avoid any issues with irritation; it’s your body, after all.

If you notice any signs of damage in the blade, such as dents or jagged edges, you should replace it immediately. This is relatively inexpensive and completely reusable, making it an attractive option for the subculture of shaving enthusiasts.

Factors Affecting the Longevity of Safety Razor Blades

A few factors can affect how long your safety razor blade will last.

Blade Sharpness

Blade sharpness plays a crucial role in determining the longevity of a safety razor blade. The sharper the blade, the less wear and tear it will experience while shaving, thus making it last longer.

Blade Quality

Regarding blade quality, there are a few key factors to consider. First, the steel that is used to make the blade is important. Higher-grade steels will last longer and will retain their sharpness for more shaves.

Different coatings can also be applied to the blades, which can help them last longer. For example, chromium-plated blades are often considered to be better quality since they are more resistant to corrosion and wear.

Additionally, blades with multiple layers of steel are often seen as of higher quality since they can retain their sharpness for longer periods. While these blades may cost a bit more initially, they often pay off in the long run due to their extended lifespan.

Frequency of Use

If you are a daily shaver, then you should expect to replace your blades after a week or after six shaves. This is because the constant wear and tear on the blade will make it dull more quickly. If you shave less often, the blade will last longer, as there will be less wear and tear.

Stropping and Honing

While most users won’t strope a razor blade, and it’s primarily used for a straight razor vs. a safety razor, you can still sharpen them. Stropping is a sharpening technique that involves running a blade along a leather strip to realign and restore the blade’s edge.

Honing is a refinement process of stropping, and it involves using a very fine grit stone to sharpen the blade further. These processes should be done after each use to ensure maximum performance and longevity. By regularly stropping and honing your safety razor blade, you will be able to get the most out of it and make it last for months or even years.

However, it is important to note that over-sharpening the blade can dull faster. Therefore, it is best to maintain a balance between keeping the blade sharp and not over-sharpening it.

How Do I Know if My Safety Razor Is Dull?

To know if your safety razor is dull, it is important to pay close attention to the blade and its performance. If you feel a pulling sensation or have difficulty gliding the blade over your skin, the blade is likely getting dull.

Additionally, if you notice any blunting or wrinkling of the blade, it is time to replace it. To check for dullness, you can use the thumbnail test: allow the blade to slide along your thumbnail, top to bottom. If it catches immediately, it is sharp.

However, if it glides or skips, the razor is dull. Repeatedly rinsing the razor after every two or three swipes can also help prevent dullness and ensure the blade glides smoothly. Also, checking your blade pack for alignment and evenness can indicate when it is time to change blades. If the blade looks crooked in the pack, it will likely be too dull to use.

Lastly, you can tell if your razor is dull by feeling your stubble: if it’s painful and your significant other avoids kissing you, it’s time to switch out your razor!

Can You Make Razor Blades Last Longer?

If you want to make your razor blades last longer, you can do a few things.

First, store your blades in a dry place and away from moisture. Also, make sure to clean the blade after each use. This will help prevent bacteria from building up and make it last longer.

It is important to use a sharp, clean razor blade to ensure the best shave possible. Dull blades are more likely to cause nicks and cuts, so it is important to replace them as soon as possible. Rinse and wipe the inside of the razor head when you change blades for maximum efficiency and safety.

It is also recommended that you use good quality shaving cream or soap to help protect your skin and provide a smoother shave. Remember that safety razors require more attention to blade replacement than other razors, so it is important to be mindful of how often you need to change your blades.

What Happens When You Use an Old or Dull Razor Blade?

Each time you use a razor blade, the metal is subject to oxidation, which reduces its sharpness. This oxidation can cause the blade to be duller than usual, leading to a rougher shave and more chances for cuts and irritation.

It is important to replace the blades after a week of shaving and more if they show signs of rust. To ensure sharpness, razor blades should be replaced regularly as needed. Follow these tips for a safe and close-shave experience!

Replace it or face the consequences

When your razor blades get rusted, they can be airborne and oxidize your safety razors. Safety razors are designed to be reused and can last for years with proper care. Not only does this make them a great value.

The blades of a safety razor are relatively inexpensive, often costing no more than 10-40 cents each when bought in bulk. And because the blades are so affordable, you’ll never hesitate to toss them after a single use, which means you can enjoy a perfect shave every time! So, before you shave with a rusted blade, consider your face and skin and think twice.


When it comes to shaving, there is a whole subculture of enthusiasts who have a passion for this daily ritual. While some guys use a fresh blade every time, others routinely get 100 shaves from a single blade. This is not to mention the safety razor blades that are relatively inexpensive and completely reusable.

Just because i'm asian does not mean I don't need shaving. I always wanted to grow a beard when I was young, now I need to shave because hair growth for me is a problem. I'm going through what every man will and has gone through before.
