Hair Scissors Blades and Edges USA Guide - Japan Scissors USA

There are different types of hair scissors edges and blades. We’ll go in-depth into the various types and tell you all you need to know about them.

There first two significant types of hair scissors blades that we’ll look at are the single bevel or flat blade and the out-curved blade.

The single bevel or flat blade is best used for cutting lightweight hair. The out-curved blade is better suited towards softer hair.   

Here is a comprehensive look at them and other blade types.


The best hair cutting shear blades for hairdressing

The most common type of scissors blade is the flat single bevel blade. It’s the typical standard used for all barbershops.

It’s also the easiest blade to use of all. With this blade, a barber can quickly achieve a smooth cut.

The flat surface makes it suitable for hair and face.

It has been in use for ages, and it remains a strong force to be reckoned with. It also has the added advantage of being affordable.

While remaining efficient, the blade relies on pressure and force from the barber.

A major disadvantage of this blade is that it can’t be used for complex hair cutting styles.

There are two types of convex scissors blades. They include the convex shape blade and the convex pro blade.


The Convex Shape blade is a sharp, soft blade that works fine for anybody. It is a slight technological improvement over the Convex Pro blade.

This blade type can be used for any style of cutting, but it is best used for point cutting, texturing, and slide cutting.

The Convex Shape blade has sharp edges that rub each other along the hollow side of the edge.

To prevent the frictional rubbing from occurring, there is a hone line in the hollow along the edges.

This thin, flat hone line is on the hollow side of the edge, and it can be seen from the top part of the scissors, and it extends to the back.   


The Convex Pro blade has a very sharp blade setting and angle. It also has a powerful and large cross-section. Since the blade point is very tiny and sharp (smaller than a hair), hairs won’t fly about. 

This is the right blade to use if you want to achieve a sharp cut, thanks to its curved outer blade. It’s also great for slide cutting and any other advanced cutting technique.

The sharp cutting edge angle makes the convex blade well-suited for smooth cuts and sharp, suave looks. 

The Convex Pro blade is more difficult to produce and more expensive than other types. 


Hair cutting shear blades

The Sword Shape blade is shaped like a sword, with power concentrated at the point of the blade. It also comes with a convex edge.

The sword blade delivers precise, quality cutting. It also has a ridge across the blade’s length for helping it to achieve crisp, powerful cuts regardless of the length.

This isn’t like other blade types where the length of the blade determines the power of the blade. This blade works just as advertised.


The Concave Shape blade is designed for an efficient cutting experience. It’s cutting load is lower than other scissors, and this helps to improve efficiency and ease.

The two major types of Concave shape blades are Micro-serrated and Serrated blade. The serrated and micro-serrated blades usually come with a beveled edge blade.

Micro-serrated blades are best for beginners as they stop hair from sliding downwards the blade.

These blades are suitable for dry hair and detail cutting. The blades work best for scissors as opposed to comb cutting.

The edge of the serrated blade catches hair and obstructs pushing. This makes it good for dry cutting and wigs. Most newbies learn with the serrated blade.

The major disadvantage of the serrated blade is that it often holds the human hair like a comb, and it could harm the cuticles as it sweeps through the hair.

The hardness of the scissors metal, the shape and size of the curved blade line radius and the cutting edge always determine the type of cutting that a scissors is used for and how the scissors cuts.

Slim, long scissors with narrow blades are better suited for heavy point cutting and unsharpened work.

The angle of a slim, long blade scissors edge is about 50⁰ to 55⁰. This kind of scissors also has a blade line radius within 900mm to 1000mm.

The more the blade width, the stronger the blade is when it cuts hair. Thin, slim blades are good for light, detailed haircuts.


Blade lines could range from straight blade lines to curved blade lines.

Standard blades are usually called willow blade, straighter blades are simply called straight blades, while curved blades are usually known as bamboo leaf blade.

The more straight a blade is, the easier it is to cut hair without the hair sliding down the blade. The curvier a blade is, the more the blade will slide down the blade for a softer, smoother cut.

The scissors with the biggest curve is the bamboo leaf blade, which is best used for slicing and slide cuts.
