When Should You Change Your Razor Blades
The argument here is quite diverse, as every type of razor blade, every brand, and depending on the user will affect the time frame for a blade to stay sharp.
Depending on how often you shave and how coarse and dense your beard is, a good-quality brand razor should give you 5-10 shaves, except for a few.
Some razors will only give you around three to four uses.
In the end, this adds up to over two weeks on average.

Lifespan of Cartridge, Electrical and Safety Razors
But let’s go a bit further into the general lifespan and some other details of every type of razor blade, the Cartridge; Electrical and Safety Razor
Cartridge Razor Blades
Please don’t confuse this one with your disposable razors or single-piece razors. Your Cartridge razor has an ejectable blade head, which means you can easily remove and replace the blade head, as seen in the picture.
This system allows you to keep the handle and regularly replace the head.
Unfortunately, Cartridge razors’ blades or heads are quite expensive; sometimes, the blades are even more costly than the entire razor.
A good quality Cartridge razor should last you around 30 shaves, taking that you do take care of your razors.
In most cases, with rough and irresponsible use, such as applying excessive pressure or not cleaning the razor after use, you can expect no more than 20 shaves from a good-quality brand.
Safety Razor
I have included a picture of the old-fashioned, vintage-styled Safety Razor, although some more advanced and modern designs are available today.
The Safety Razor has blades that are significantly shorter than those found in Cartridge and Electrical Razors. These blades are reasonably cheap to replace and generally do not last very long.
A good-quality safety razor brand can give you around six shaves or about a week of use if you shave regularly.
Electrical Razor
Every brand has a manufacturer’s recommendation for when to change the blades on Electrical Razors.
For example, Braun, one of the top brands in electric razors, recommends changing razor heads every 18 months.
Electrical Razors are expensive, highly efficient, and handy without shaving cream or water. Replacing the blades is just as costly, although they need replacing much less than any other type.
