When it comes to precision cutting, scraping, or industrial trimming, few tools match the single edge razor blade in simplicity and effectiveness. Though small, these blades are engineering marvels—crafted with precise edge angles and facet geometries that determine their sharpness, strength, and durability.

In this guide, we’ll break down how blade facets and angles affect performance, the differences between 2-facet and 3-facet blades, the best scrapers and compatible handles, and where to buy high-quality single edge razor blades made in the USA by Excel Blades.

Understanding Single Edge Razor Blades

A single edge razor blade features one sharpened edge and a reinforced back, giving it structural stability and safety. These blades are used across industries—from industrial manufacturing and construction to crafting, model building, and restoration work.

Unlike double-edge blades, single-edge blades are inserted into scrapers, hobby knives, or specialized handles, allowing precise control for cutting, shaving, or scraping various materials such as vinyl, paint, plastics, and adhesives.

Common Materials Used in Single Edge Blades

• Carbon Steel: Offers exceptional sharpness and easy resharpening; ideal for general-purpose use.
• Stainless Steel: Provides corrosion resistance and durability—perfect for use in humid or chemical environments.
• Ceramic-Coated Steel: Reduces friction and improves longevity for heavy industrial applications.

At Excel Blades, all single edge blades are engineered to meet American manufacturing standards, ensuring superior edge retention and consistent performance.

Single Edge Razor Blades: 2 Facet vs 3 Facet

One of the most overlooked yet crucial aspects of razor blade design is the number of facets—or the angled surfaces that form the cutting edge.

What Are Blade Facets?

Facets are the micro-angled planes ground into the blade edge to create sharpness and cutting efficiency. The number of facets directly affects the edge strength, sharpness, and longevity.

2-Facet Blades

A 2-facet single edge blade is the most common and practical design for general use. It has:

• Primary bevel: The main angle that creates the sharp edge.
• Secondary bevel: A supporting angle that strengthens the edge tip.

Advantages of 2-facet blades:

• Easier to produce and sharpen.
• Ideal for scraping, trimming, and everyday industrial applications.
• Offers a durable edge that resists chipping.

2-facet blades are often used with metal scrapers and utility tools in construction, packaging, or maintenance.

3-Facet Blades

A 3-facet single edge blade has an additional micro-bevel at the edge tip, providing a finer cutting angle.

Advantages of 3-facet blades:

• Extremely sharp for precision cutting (e.g., film, paper, or vinyl).
• Reduced cutting force and smoother glide.
• Improved control for delicate applications.

However, 3-facet blades may dull slightly faster under heavy use due to their finer edge.

Excel Blades manufactures both 2-facet and 3-facet designs, offering professionals and creators flexibility depending on their tasks.

For example, if you’re in sign making or vinyl installation, the 3-facet razor blade will deliver a cleaner cut, while industrial users may prefer the 2-facet version for durability and resilience.

Blade Angles and Edge Geometry

The angle of a single edge blade determines its performance characteristics. A smaller edge angle produces a sharper blade, while a wider angle improves strength and wear resistance.

Typical single edge blade angles range from 17° to 22° per side, depending on the intended application.

• 17°–19°: Best for fine cutting and light materials.
• 20°–22°: Ideal for tougher materials or scraping.

Excel Blades engineers its razor edges with precision-ground angles to achieve optimal sharpness and durability, using proprietary honing and polishing processes.
