Be it straight, rotatory, disposable, cartridge, or any razor you use; stropping it will do wonders in keeping the razor sharp and ready.

Stropping includes rubbing the razor blades through a cloth for getting rid of the unwanted stickiness that often causes trouble during shaving.

Stropping is a very simple and quick process to get the sharpness and shine of your razor blades back.

Here is a simple step to step guide to strop any of your razors easily after every 5-6 shavings. Make sure you follow the sequence and do as mentioned.

1. Clean The Razor:

Many men prefer sharpening razor blades before shaving. After all, cleaning razor blades is an important prerequisite to protecting skin from germs.

But if you’ve been ignoring this step, then do clean the razor blade from now on before stropping as it ensures no barrier between the razor blades and the leather jeans.

For cleaning, take a bowl of lukewarm water and add some drops of liquid soap to disinfect the razor blades.

You can also soak the razor in alcohol for a few minutes to kill the bacteria and germs that razor blades might have caught after the last shaving or during the time it was stored.

Gently swirl the razor into the water and see if it gets rid of all the dirt, hair follicles, stickiness, and gunk from the blades. Next, dry the razor with a blow-dry or pat it with a clean towel before jumping to the stropping.

2. Pick The Right Materials For Stropping:

To perform stropping, you simply require an old pair of leather jeans or any leather cloth that you no longer use, the razor blades that need to be sharpened, and a pair of gloves if you are afraid of cutting yourself during the process.Pick The Right Materials For Stropping razor

However, many people fail to distinguish between leather and other materials and thus don’t get the desired results.

Choose a leather material that is hard, resistant, and isn’t ripped at the area which you’ll be stropping.

Denim or canvas tote works best for stropping the blades of any razor. Remember the material may be rugged, damaged, or frayed during stropping.

3. Strop The Blades:

Once you’re done cleaning and drying the razor, it’s time to stop it down by using your old pair of leather jeans and get the sharpness back.

Let’s walk through the steps:

  • The first step is to place the jeans on a flat, smooth, and sturdy surface which can be any wooden table or the marble floor of your room. Make sure the place is not delicate and surrounded by objects as they may get damaged during stropping. Never Strop on the sink, bed, or any uneven or wet surface as it can limit or cause disturbance in your sharpening motion.
  • Then, run the razor along the length of your jeans approximately 15-20 times. To decide which direction you should strop in, follow the grain rule which means stropping in the direction of blades and your hair growth. Always use the same motion in which you did the first strop and continue it by applying moderate pressure on the razor blades in short and quick strokes to sustain a good stropping speed.
  • Once done in the same direction for the mentioned time, strop the razor blades again on another area of the jeans but in a different direction. Keep switching the directions till you feel that the razor has been thoroughly cleaned and sharpened for the next time you do shaving.
  • Repeat the same process for as many blades as you want and check the razor by shaving a patch of your hair on the forearm. Also, keep the pointed edge of the razor away from you or in the opposite direction so that you unintentionally don’t harm yourself with the efficient speed you’re stropping in.
  • After stropping, rinse the razor blade with hot water and shake it off on the sink to lose excessive water. Lastly, if you’re shaving right after stropping then don’t forget to apply a good skin care regimen before shaving. Stropping the razor blades indeed make a huge difference while shaving as the razor blades will now easily glide over the hair and eradicate it from the follicle.
