In general terms, there are three major types of hair scissors edges. They include the serrated scissors edge, the bevelled scissors edge, and the convex scissors’ edge. These will be described in detail, along with other types of blade edges and shapes.
The most popular scissor edge or blade in Canada is the Convex Edge and the Bevel Edge.
The most popular kind of scissors blade is the single bevel blade. Its popularity is also why it is known as the standard blade. It is a lightweight, flat blade that gives a very smooth cut.
This blade also works very fine for both the hair and the comb face. Its design remains the most popular one for hair shear production. Its cutting efficiency is almost unparalleled.
It also has the added advantage of being one of the cheapest scissors that you can buy.
But when using the flat, single bevel blade, you need to apply more force and pressure than you would need for the other commonly found blades in the market today.
Another disadvantage is that you can’t use this blade for elaborate hair cutting styles.
The convex scissors blades come in two varieties. The two varieties include the convex pro and the convex shape blade.
The Convex Pro is a mean, slick sharp-angled blade. It has the sharpest cutting angle and blade. This blade is designed for barbers looking to give their clients a smooth, sharp cut.
It is a strong, powerful design that makes for sharp, smooth haircuts.
It has a manual finish desired by the barber for an artistic cut. The blade’s cross-section is larger and powerful than the standard scissors blade. Hairs won’t fly about when using this scissors, thanks to its blade point that is finer than hair.
The convex pro blade’s curved outer surface encourages slide cutting and any other pro-level cutting style.
The unique strengths and dynamics of the convex pro blade make it a tougher blade to produce the others. It also makes it a costly blade, designed for high-end or professional users.
The Convex shape is an improvement over the regular convex blade. But it retains the sharp, soft cut of the original blade. It can be used by anyone, whether amateur or professional.
It also has the added advantage of being dynamic and applicable for any hair cutting style or system. It works fine for point cuts, slide cuts, and hair texturizing.
The convex shape blade has sharp edges that rub one another on the hollow part of the blade edge. To stop the edges from rubbing each other, manufacturers added a flat, thin hone line from the tip to the end of the scissors.
Taking naming inspiration from its shape, the sword shape blade is sword-shaped. And like a sword, the tip delivers a lot of power. Also, it has a sword blade and a convex edge.
The sword blade works to give the blade power and precision. The sword blade has a ridge that runs down the blade’s length. The ridge helps the blade to give powerful cuts regardless of blade length. So, the blade’s length doesn’t affect the blade’s power.
The cutting load of the concave blade is lower than other scissors blades. It is designed to cut hair with ease.
Concave blades include micro-serrated blades or serrated blades. Both types of blade are typically used together along with a bevelled edge blade. Micro-serrated blades have the added advantage of preventing hair from sliding down the scissors blade.
The blade’s edge catches the hair and prevents pushing, making it suitable for wigs, dry cutting, and scissor over comb. A lot of new barbers learn using serrated edge scissors as it is user-friendly. But, it has the added disadvantage of damaging the cuticles when it moves through the hair.
The width of hair scissors varies. But, the wider the blade, the more the power of the blade when cutting hair. Thin blades are more suitable for detailed work.
Slim, long blades work fine for heavy point cutting. They typically have an edge angle of 50⁰ to 55⁰, with a blade line radius within 90cm to 100cm.
The shape of the blade radius (the size of the blade line radius), the metal hardness, and the cutting edge determines how a scissors cuts and the cutting that it is meant for.
There are several types of scissor blade lines, and they vary from curved blades to the straightest blades. The straightest blades are called ‘straight blade,’ the curved blades are called ‘bamboo leaf blade,’ and the ordinary blades are known as ‘willow blade.’
The best blades to hold for cutting hair without sliding are the straight blades. The higher the curve, the higher the amount of hair that will slide. This is useful for a soft, smooth cut. The curved blade is best for slicing and slid cuts, thanks to its large curve.
