How to Replace Blades in a Safety Razor


Shaving has been one way to groom oneself and has been a practice, particularly among men, since ancient times when people used two shell halves to remove unsightly hairs. People began using straight razors around 3000 B.C. This went on for a long time until the invention of the safety razor in the late 18th century. The blades of a safety razor can be replaced if they get dull, whereas straight razors have to be sharpened.

Today, safety razors remain of the most popular ways to shave. After using it several times you will need to replace the blades. Several safety razors are on the market and it is important to know what type you are using before buying a replacement. Traditional safety razors allow you to open the cartridge, remove the blade and replace it with a new one. Another other type requires the whole cartridge assembly to be replaced. All it takes is snapping the new cartridge in and you are good to go. It is relatively easy to replace blades on these traditional safety razors, so absolutely anyone can do it.

Things You'll Need

  • Safety Razor
  • Blade

Normally, double-edged thin blades come in envelope-type paper wrappings. Open the wrapping carefully, making sure your fingers do not come in contact with either of the two broad edges because these are very sharp and you could cut your fingers.

Repeatedly twist the bottom part of the safety razor handle until its cartridge bay opens. Make sure that the restraining covers no longer impede the removal of the old blade

Carefully lift the old blade from the cartridge by taking hold of the two narrow edges with your thumb and forefinger. You may want to shake it a little first before lifting to ensure that there are no sticky leftover materials that hold the blade down.

Clean the bare cartridge by holding it under a faucet then shake it repeatedly until it is free of water droplets. This is to remove any vestige of unwanted materials, like shaving cream, sticking on the cartridge.

Take the new blade, handling it just like the old blade, and slowly fit it into the cartridge slot. Check if the new blade is lying flatly and evenly on the cartridge because any tilt on the blade will cause it to break when you try to close the cartridge.

Twist the bottom part of the handle again, this time in the opposite direction until the cartridge is fully closed and secure. Your safety razor is now ready for use.

Tips & Warnings

  • You may want to wash the empty cartridge thoroughly with running water. It cleans out any leftover material that could act as glue to the blade.
  • As the title indicates, we are working with razor blades, so mind your fingers.
