How long do safety razor blades last? Using a dull blade can lead to all sorts of issues. Dull blades cause hair pulling and increase your risk of razor burn and skin irritation. Knowing when to change out razor blades is vitally important.
On the more severe end of things a dull razor blade can cause skin bacteria issues. This leads to skin infections and medical issues. It's easy to avoid all these problems by knowing when your razor blade is due for a change.
Is It Time to Change Safety Razor Blades?
There are several factors that determine how often a blade should be changed. Generally safety razor blades last 7 days. This is going to vary from person to person but one week is a good rule of thumb to use per blade.
When you first begin to feel the blade tug at your whiskers you can change it out. Safety razor blades are so affordable that there's no reason to continue using a imperfect blade.
Here's some factors that can make your safety razor blade last longer or dull quicker.
Safety Razor Blade Brands
Some safety razor blade brands are known to last a little longer than others. With not a big difference in cost you can experiment with different blade and see what results you get. I've heard time and time again from enthusiasts that their Feather blades last them the longest.
If you don't have a lot of experience with the different blade types then try a variety pack. Variety packs give you a couple blades from different brands so you can compare them yourself.
The type of safety razor you're using can play a slight role. Open comb razors that expose more of the blade may see blades dull quicker.
How Many Passes Do You Make?
One of the standard shaving patterns is a three pass shave that goes with the grain, cross grain, and against the grain. Some people change their shave up in order to compensate for sensitive skin or out of personal preference.
If you're able to get a good shave while making fewer passes you'll extend the life of your razor blade. I enjoy doing a two pass shave (WTG & XTG). I avoid going against the grain to greatly reduce my odds of getting ingrown hairs, razor burn, and skin irritation.
If you get accustom to a two pass shave similar to what I use then you can benefit from a longer lasting blade as well.
How Frequently Do You Shave?
If you really want to take the life of your razor blade to the next level then go a day without shaving. With an electric shaver you can alternate between your safety razor and your electric shaver.
This is the best way to extend the life of your safety razor blade. Plus you're not always in the mood to go through the wet shaving process every morning. Owning an electric shaver lets you get a quick convenient dry shave in between razor blade days.
While the immediate cost of having to purchase an electric shaver is high you're going to save more money in the long run. You can technically double how long your safety razor blade lasts.
Consider Changing Blades Sooner
While doing what you can to get the most out of your blades is fine you may want to just consider changing blades sooner. You can buy safety razor blades as low as $0.10 per blade. So changing out your razor more frequently isn't a big problem.
If you want to always have a blade that's super sharp, without putting any effort into extending the blades life, consider changing blades three times a week. Replacing a safety razor blade three times weekly is the gold standard of always having a very sharp blade.
If you go the full life of a blade (roughly 7 days) you'll notice it isn't as sharp as the day it came out of the box. It'll slowly become less sharp as you shave every day and after day 7 should be replaced. Even while it isn't as sharp say on day 5 it can be used quite easily.
Changing your blade three times a week is for the real stickler in my opinion. However, I'll let you be the judge and decide if you think changing blades three times a week is worth it.
How To Make Your Blade Last Longer
If you're interested in a couple tips and tricks to make your safety razor blade last longer I have a few. Give some of these a try and let me know how they worked for you by leaving a comment below. Thanks for reading!
Mineral Oil - After shaving rinse and completely dry your razor by patting it dry. Then leave a jar of mineral oil on your bathroom counter and completely submerge your razor in the mineral oil while not being used.
Storing your safety razor in mineral oil prevent oxidation from air drying. This prevent the blade from degrading and can extend the life of your blade immensely.
Blue Jeans - Run your safety razor blade upwards against a pair of old jeans after every shave. The jeans will sharpen the blade after each use and you'll have a fresh blade in the morning. Doing this can extend the life of your safety razor blade by a week.
I hope you enjoyed this article and these little tricks. How long do safety razor blades last really depends on you and your actions. If you're the frugal type you can really get a lot of extra life from your blade but if you're not then maybe go with the standard of replacing your blade three times a week.
