Although the majority of razor blades often come from stainless steel, they can be made from carbon steel. While stainless steel is best-known for its corrosion resistance and durability, carbon steel is favored due to its hardness.

Besides material, the coating is an essential factor that you should pay attention to when selecting razor blades. The coating is added to boost rust prevention, lubrication, and minimizes clogged hairs that facilitate smoother cleaning. It is also supposed to prevent dullness, thus prolonging the longevity of the blades.

To choose a perfect coating, you can refer to some information as below:

  • The platinum coating is one of the most popular coatings for razor blades. Its durable component allows for a sharper and precise blade with smooth sides.
  • PTFE coating helps the blades to glide effortlessly across the face, thus reducing irritation. 
  • Chromium coating is also a well-known coating. It helps the blades last longer and reduces the chance of corrosion, which prevents the blade from becoming dull and causing cuts on the skin.
  • Like chromium, the ceramic coating helps to enhance the durability of the blades and maximize corrosion resistance, allowing the blades to stay sharp over time.


Comfort is a prime consideration when buying razor blades. If a blade is able to glide smoothly over your skin without causing nicks, cuts, pulls, or razor bumps, then it should be worth your investment.


Durability is one of the most fundamental parts when picking the most desirable razor blades for your pleasant shaving set. While some razor blades can last several shaving sessions without becoming dull, others may stand a few sets.

Hence, if you don’t want the blades to go dull quickly and are tossed into the garbage, you should invest in a more durable blade. Thus, it also comes with greater efficiency and lower cost per shave.
