The Ultimate Guide to Single Edge Razor Blades: Choosing the Perfect Blade for a Smooth, Precise Shave

What are single-edge blades?

Single-edge (SE) razor blades are precision-engineered blades with a single sharp cutting edge, ideal for shaving, grooming, and professional barbering. Unlike double-edge (DE) blades, which have two cutting sides, SE blades expose only one edge, providing users with superior control and accuracy.

These blades are commonly used in safety razors, shavettes, and some straight razors, resulting in a smooth, close shave with minimal irritation. Their sharpness and precision make them a popular choice for barbers and grooming enthusiasts alike.

While single-edge blades were traditionally used by professional barbers, they are now increasingly found in modern razors that combine the convenience of cartridge-style systems with the precision of single blades. Single-edge razor blades, whether used for daily shaving or detailed grooming along the skin line, provide a consistent, clean-cut experience that rivals many multi-blade systems.

How Do Single Edge Razor Blades Compare to Double Edge safety Razor Blades?

Single-edge blades might appear simple, but their design is critical for a close, comfortable shave. In contrast to double-edge blades, which have two cutting sides, these blades have only one exposed edge, allowing for more precise control and focused pressure—especially useful for beginners or detailed grooming.

Because only one side is used, they need to be replaced more frequently than double-edge blades, which can be flipped to extend their life.

Many people refer to SE blades as barber or "half" razor blades, but some are purpose-built as dedicated single-edge designs, rather than just split DEs. These specialized blades are designed for specific razors and shaving styles.

Stainless steel is the most common material for single-edge blades, but carbon steel is also popular. Carbon steel is valued in barbershops for its superior edge quality, even though it provides less rust protection because blades are frequently changed between clients.

Modern single-edge razors have a distinct design. They are typically thicker and have a distinct edge angle, allowing for a wider range of cutting angles, which improves both performance and durability. SE razor blades, which were originally adapted from industrial blades used for cutting paper, film, or textiles, are frequently coated with PTFE (similar to Teflon) to reduce friction and improve glide.

Single-edge blades are available in a variety of designs depending on the brand and are typically sold individually wrapped or in injectors, making replacement simple, safe, and convenient.

Different Single-Edge Razor Systems

Barber Razor

A barber razor, also known as a straight razor, shavette, or cutthroat razor, is a traditional grooming tool that employs a single-edge blade, which is often half double-edged. These blades can be manually snapped from a standard double-edge (DE) blade or pre-cut to fit barber-style razors.

Professional barbers prefer these blades because they are thin and razor sharp, allowing for precise control while shaving. The design also allows for quick and hygienic blade changes between clients, which is essential in professional settings.

Barber single-edge blades are compatible with a variety of straight razor handles and shavettes, making them an affordable option for a close, clean shave. Whether for professional grooming or traditional wet shaving at home, these blades provide a consistent and sanitary shaving experience.

Leaf Razor

The Leaf Razor is a modern system with a multi-blade cartridge that takes half double-edge blades. It is compatible with a wide range of blade brands, but platinum-coated stainless steel blades are recommended for best results.

The multi-blade head's enclosed design may limit water drainage, allowing moisture to remain on the blades between uses. Using stainless steel blades prevents rust and buildup, resulting in a smoother, longer-lasting shave.

Supply Razor

The Supply Razor makes use of injector-style blades, specifically Feather's Artist Club Professional blades manufactured in Japan. These blades are thicker and stiffer than traditional double-edge or half blades, resulting in greater durability and a consistently smooth shaving experience.

While more expensive, many users feel the enhanced performance and comfort justify the cost. This system is ideal for those seeking a modern, high-performance single-edge razor with a premium feel.

OneBlade

OneBlade razors are compatible exclusively with Feather FHS-10 single-edge blades, which are significantly thicker than double-edge or Artist Club blades. These rigid stainless steel blades resist flexing or curling, providing a smooth, consistent shave.

Derived from industrial scraper blades and coated with PTFE, these blades are durable enough for multiple shaves. Although the higher cost per blade may be a downside compared to traditional DE or half blades, OneBlade offers a consistent shaving experience with fewer blade changes.

Best Single-Edge Razor Blade Brands on the Market

When it comes to single-edge razor blades, a few brands stand out for their performance, but professional barbers and discerning shavers frequently prefer blades that provide superior sharpness, durability, and a gentle shave.

My-Blades platinum-coated stainless steel blades are a top choice among barbers due to their precision, smoothness, and consistent performance. These blades are designed for hygiene and broad compatibility with straight razors, shavettes, and cutthroat razors, resulting in a close, irritation-free shave with a gentle touch, making them ideal for both professional and home use.

Derby and Dorco are solid entry-level options for barber razors and shavettes with half double-edge blades. These inexpensive blades provide adequate sharpness and comfort, making them ideal for beginners or those looking for an affordable daily shave. Permasharp by Gillette is a good alternative, known for its durability and clean-cutting edges.

Whether you're a professional barber or a shaving enthusiast, using high-quality blades like My-Blades can make a big difference in getting a smooth, precise, and enjoyable shave.

Step-by-Step Guide to Shaving with a Single Edge Razor

Single edge razors provide a traditional, controlled shaving experience similar to double edge (DE) razors, but with the added precision of a single visible blade edge. These razors are ideal for both novice and experienced wet shavers, allowing for smooth, irritation-free shaves when used properly. Follow this step-by-step guide to master shaving with a single edge razor.

1. Prepare Your Skin

Start by softening your facial hair and moisturizing your skin. Wash your face with warm water or shave immediately after a hot shower. Using a pre-shave oil can reduce friction between the razor blade and skin, providing extra glide and protection.

2. Apply a Quality Shaving Cream or Foam

Single edge razors lack built-in lubrication strips, so using a rich shaving cream, foam, or gel is essential. A good lather lifts hair and allows the razor blade to glide smoothly, ensuring a clean, precise cut.

4. Insert the Blade into Your Razor

Carefully place a new single edge razor blade into your razor according to the manufacturer’s instructions. Whether using an injector, Artist Club, GEM-style, or barber razor, make sure the blade is secure. Always handle blades by the sides to prevent cuts.

4. Shave with Light Pressure

Hold the razor at roughly a 30-degree angle, similar to a DE razor. Use short, controlled strokes, letting the weight of the razor do the work—avoid pressing down. Start shaving with the grain to reduce irritation.

5. Rinse Between Strokes

Rinse the blade under warm water every few strokes to remove lather and hair buildup. This keeps the edge razor-sharp and efficient throughout your shave.

6. Optional: Re-Lather and Shave Against the Grain

For an ultra-close shave, reapply lather and carefully shave across or against the grain. This step is optional but can provide a smoother finish if done gently.

7. Rinse and Apply Aftershave

After shaving, rinse your face with cool water to close the pores. Pat your skin dry with a clean towel. For added protection and to reduce any minor nicks or irritation, you can gently rub an alum stone over the shaved areas—this helps tighten pores and acts as a natural antiseptic. Follow up with a soothing, alcohol-free aftershave or balm to nourish and protect the skin.

8. Clean and Store Your Razor

Rinse your razor thoroughly, dry it, and store it in a dry place to prevent rust or corrosion—especially for stainless steel or carbon steel blades. Replace the blade regularly to maintain sharpness and hygiene for every shave.

Summary:

Shaving with a single edge razor is similar to shaving with a double edge razor, except that the one-sided design provides more control and precision. It's an excellent choice for wet shaving enthusiasts looking for a closer shave without the use of barber-style straight razors or shavettes. With proper technique and preparation, you can get one of the best shaves you've ever had.
