Double Edge Razor Blade: The Difference Between Stainless Steel, Swedish Stainless Steel, and Carbon Steel


When it comes to shaving, choosing the right razor blade material can make a significant difference in user’s shaving experience. Double edge razor blades are a popular choice among wet shavers due to their versatility and close shaving capabilities. In this article, we will explore the differences between four common materials used for double edge razor blades: 4cr13 stainless steel, 6cr13 stainless steel, Swedish stainless steel, and carbon steel.

The difference between stainless steel and carbon steel

Before diving into the specifics of different materials, it’s essential to understand the significance of material selection when it comes to double edge razor blades. The material used can affect various aspects, including the blade’s durability, sharpness, and overall performance.

1. 4cr13 Stainless Steel

4cr13 stainless steel is a popular material choice for double edge razor blades. It is a type of martensitic stainless steel known for its corrosion resistance and toughness. The “4cr13” designation refers to the composition of the steel, which includes 4% chromium.

Properties and Characteristics

  • Good corrosion resistance
  • Moderate hardness and edge retention
  • Easy to sharpen
  • Affordable

Pros and Cons


  • Corrosion-resistant, making it suitable for wet shaving environments
  • Offers a balance between sharpness and durability
  • Budget-friendly option


  • Not as durable as some other materials
  • May require more frequent blade changes

2. 6cr13 Stainless Steel

Similar to 4cr13 stainless steel, 6cr13 stainless steel is also a martensitic stainless steel with increased chromium content. The “6cr13” designation indicates 6% chromium in its composition.

Properties and Characteristics

  • Improved corrosion resistance compared to 4cr13
  • Good hardness and edge retention
  • Relatively easy to sharpen
  • Cost-effective

Pros and Cons


  • Better corrosion resistance than 4cr13 stainless steel
  • Provides a good balance between sharpness and longevity
  • Affordable option for wet shavers


  • Not as durable as higher-grade stainless steels
  • Regular blade changes may be required for optimal performance

3. Swedish Stainless Steel

Properties and Characteristics

  • Excellent corrosion resistance
  • High hardness and edge retention
  • Requires more effort to sharpen
  • Relatively expensive

Pros and Cons


  • Superior corrosion resistance, suitable for prolonged exposure to water
  • Provides excellent sharpness and long-lasting performance
  • Preferred choice for wet shaving enthusiasts seeking premium quality


  • Higher cost compared to other materials
  • Requires skill and patience for sharpening

4. Carbon Steel

Carbon steel is a traditional material used in razor blade manufacturing. It is known for its exceptional sharpness and edge retention but requires careful maintenance to prevent corrosion.

Properties and Characteristics

  • Exceptional sharpness
  • High hardness and edge retention
  • Prone to corrosion if not properly cared for
  • Requires more skill to sharpen

Pros and Cons


  • Unparalleled sharpness and cutting performance
  • Excellent edge retention for an extended period
  • Preferred by experienced wet shavers who prioritize sharpness


  • Susceptible to corrosion without proper drying and maintenance
  • Requires more expertise to maintain and sharpen

Comparing the Blade Materials

When choosing a double edge razor blade, it’s crucial to consider the following factors:

Durability and Sharpness

  • 4cr13 and 6cr13 stainless steel offer a good balance between durability and sharpness.
  • Swedish stainless steel provides exceptional durability and sharpness.
  • Carbon steel offers unparalleled sharpness but requires careful maintenance to prevent corrosion.

Corrosion Resistance

  • 4cr13 stainless steel provides moderate corrosion resistance.
  • 6cr13 stainless steel offers improved corrosion resistance compared to 4cr13.
  • Swedish stainless steel provides excellent corrosion resistance.
  • Carbon steel is prone to corrosion if not adequately cared for.

Maintenance and Care

  • Stainless steel blades are relatively easier to maintain compared to carbon steel.
  • Carbon steel blades require diligent drying and occasional oiling to prevent corrosion.
