blade for hair
25 May

Cutting your hair seems like a simple task. First, you pick up the scissors or the clippers, then you cut your hair.

However, most of us are not beauticians, so we lack the proper knowledge of how to properly cut our own hair or what equipment to use when doing so. Finding the correct blade for any hairstyle and hair type is based on:

  • The kind of haircut or hairstyle
  • The texture of the hair
  • The thickness or thinness of the hair

The Best Blade for Hair

Beveled edge blades are the most common and universal shears for cutting hair. However, the beveled edge has limitations. You can not use beveled edge blades for many advanced haircuts, and they require an extreme amount of force to cut.

The convex edge blade is an excellent alternative and an overall better choice. Although it can be slightly more expensive, the convex-edged blade has more comprehensive capabilities and range.

What Can the Bevel Edge Blade for Hair Do?

Bevel edge hair shears are acknowledged to last the width of a stylist’s career without replacement. Cosmetology trainers and experienced hair stylists recommend the beveled edge blade as a staple among hair grooming tools. It is also known universally as the German blade.

The blades of the beveled edge are extremely sharp yet durable. Beveled edges consist of either one of two options. Option one includes one serrated blade, while the second option has two serrated blades. Beveled edge blades require one or more serrated edges because it holds the hair in place and halts movement when cutting straight across or at an angle.

Besides being a universal grooming option, beveled edge blades are typically the cheapest. Beveled edge blades are excellent for simple techniques such as the blunt cut but lack the structure for more advanced options like side or point cutting.

Facts About the Beveled Edge Blade

One of the attributes of the beveled edge blade is its durability. The long-lasting effects of the blade help to maintain the health of the hair. When using the beveled edge blade, best practices require a significant amount of force and pressure to cut the hair properly.

What Can the Convex Edge Blade for Hair Do?

It is clear that you can apply a convex edge to a wider variety of hair types and hairstyles. But its functionalities do not end there. A significant component of the convex edge shears is its curved outer blade, creating a sharp cut.

The cut of the blade provides a continuous and smooth cut. These factors are significant for slide cutting, point cutting, and texturizing. However, they also make the convex edge blade more challenging to make, which makes the convex edge blade more expensive than other shears.

Furthermore, the expense is worth it; a pair of convex edge shears provide quality and long-lasting universal wear.

Facts About the Convex Edge Blade

Convex edge blades are complex to make. Their complexity means that proper use must be applied to keep up the quality of the blade and the cut. What are the appropriate ways to use a convex edge blade?

  • You must apply the correct amount of pressure to the shears. Aggressive thumb pressure can be detrimental to the blade, causing dullness and other effects.
  • You must avoid carelessly placing or dropping convex shears.

German vs. Japanese Blades for Hair

German and Japanese are the two model types when it comes to hair grooming shears. German and Japanese blades for hair have been proven to provide the best quality blades for hair.

Beveled edge blades are generally German-style, and convex edge blades are typically Japanese. Although each blade type is made differently, both grooming shear styles rely on four factors: hardness, sharpness, and handle design.


German and Japanese blades for hair are made from steel. But German and Japanese steel are very different. Grades and quality levels measure steel. German and Japanese steel each uses a high-quality level. The hardness factor boils down to what the shears are made of.

However, Japanese shears utilize a more significant amount of high-quality steel. Whereas German-style shears often apply more diverse steel options such as stainless steel, micro carbide steel, and molybdenum steel. The high-quality Japanese steel options also translate to why Japanese-style shears are more expensive.


The next component of blades for hair is sharpness, which includes the sharpness of the blade. Sharpness is necessary for hair styling and grooming. A dull blade can negatively affect the cut of the hair. Due to the quality of steel, German-style blades are prone to longevity.

Beveled edge blades are sharp enough to create the perfect blunt cut. In contrast, Japanese-style blades or convex edge blades are overly sharp. Yet, the force and pressure needed to use German-style shears demonstrate the bluntness of the blade as well.

The extreme sharpness of Japanese-style shears requires more constant upkeep than German-style blades.

In addition, the high steel quality of convex edge blades creates a less durable blade, which means that Japanese-style blades must be protected when not in use and sharpened regularly to preserve the investment of the shears.

Overall, You must sharpen German-style and Japanese-style shears a minimum of every 3 to 12 months. Upkeep will keep the blades in the best shape for hair styling and grooming.

Handle Design

One of the most noticeable features of beveled edge and convex edge blades are the handles and thumb placements, also known as ergonomics. Ergonomics is the process of designing people, spaces, or objects with the goal of interacting efficiently and safely.

German-style blades have equal sizing for both the finger and thumb. Japanese-style blades are the opposite. Convex edge blades feature extensive size options, including the finger or fingers and a smaller option for the thumb.

Like hardness and sharpness, the handle design blends with the other components of blades for hair. For example, the equal sizing of German-style blades creates the tension and pressure between the finger and thumb that can be attributed to the force used to create the cut.
