Single Bevel vs Double Bevel Razor Blades

Industrial blades come in many different shapes and sizes: single edge versus double edge, chisel versus symmetric blades... In this article, we will focus on the two types of bevels and how single bevel vs double bevel blades affect slitting. This comprehensive guide will help you choose the right blade for your industrial cutting needs.

What Is a Bevel?

First things first, to understand the difference between a single and a double bevel blade, you need to know what a bevel is. In the context of industrial blades, a bevel refers to the angled edge grinded onto the blade. This angled edge is what makes the slitting edge of the razor blade. So the bevel is the angled edge and it can consist out of multiple angles, making it a single our double bevel blade.

What's the Difference between a Razor Blade Bevel and Edge?

Often there is confusion between the edge of a blade and the bevel. Before we go any further it is important to point out the difference. The edge of a blade refers to the side of the blade that has a sharp bevel, the bevel is the angle that is grinded onto the side of the blade. The fact that a blade can have multiple sides with a bevel makes it a single edge blade or double edge blade, the use of single edge blades blades is driven by safety reasons. Further in this article we we focus on the bevels of the blade and the examples shown are symmetric blades.

Razorblade Edge Vs Bevel

What Is a Single Bevel Blade?

Single Bevel

A single bevel blade is a type of blade that has only one angle grinded on the cutting edge. This angled edge is typically ground at a specific angle to optimize cutting performance for particular materials or applications. Single bevel blades are commonly used in various industries such where precision cutting and control are essential. They offer advantages such as reduced friction and improved cutting accuracy.

What Is a Double Bevel Blade?

Double Bevel

A double bevel blade is a type of blade that has two angles grinded on the cutting edge of the blade. Typically ground at specific angles depending on the intended application. Double bevel blades are commonly used in various industries such as where force and durability are important. They offer advantages such as balanced cutting performance, increased durability, and suitability for a wide range of cutting tasks.

Is There a Difference in Slitting Between Single Bevel Versus Double Bevel Blades?

Yes, there’s a difference in slitting when using single bevel versus double bevel blades in the context of industrial slitting

Single Bevel Blades

Single Bevel Blade
  • The primary bevel on a single bevel blade has a sharp angle, making it very thin on the cutting point. This makes the knife extremely sharp, but due to this sharpness, it sacrifices durability, and the knife will become dull more quickly.
  • Single bevel blades are often preferred for applications requiring precise and clean cuts.
  • Single bevel blades are particularly suitable for materials that are prone to tearing or fraying, as they can make a sharp and clean incision, minimizing damage to the material.
  • Single bevel blades are applied to reduce grinding costs obtaining cheaper blades.

Double Bevel Blades

Double Bevel Blade
  • A double bevel blade has a primary and secondary bevel. Often the primary bevel is less sharp than the secondary, this makes the blade less sharp but improves the durability and lifetime of the blade.
  • Double bevel blades are typically used for applications where cutting through thicker or tougher materials is required.
  • Double bevel blades does improve durability and longevity compared to single bevel blades when used in demanding industrial environments.
  • A double bevel combines sharpness and longer lifetime.

Which is Better? Single Bevel or Double Bevel Blades?

Double And Single Bevel

Ultimately, the choice between single bevel and double bevel blades depends on the specific requirements of the application. Some tasks may benefit from the precision and cleanliness of single bevel blades, while others may require the cutting force and durability provided by double bevel blades. It's essential to consider factors such as material type, thickness, desired cutting quality and operational efficiency when selecting the appropriate blade type for industrial use.
