The two main processes used in shear manufacturing are cast and forged.
In the process of making a cast shear, liquid metal is poured into a mold and then allowed to harden.
Manufacturing also involves heating the metal but not until the point it becomes liquid; then, it is struck repeatedly and cooled rapidly, which impacts the molecular structure of the metal and makes it denser. This process consists of two steps, as the blade and the handle are forged separately and then welded together, which strengthens the tool even more, also making it easier to balance in hand.
BARBER SHEARS CAST VS FORGED WHICH IS THE BEST?
Generally, two kind of shears are the most popular among barbers.
A convex edge is the sharpest edge you can get on a pair of scissors. They are also known by three other names: hamaguri-ba, clam shell, and most commonly, Japanese style. All convex-edged are hollow ground on the inside of the blade which gives a very smooth cutting action. They are, however, extremely fragile and can lose their edge. Applying too much forward or backward thumb pressure, or even storing your scissors loose in a drawer or dropping them will knock the edge off the scissors.
Convex scissors are perfect for any cutting technique, but excel at slide cutting, point cutting and texturizing. Because the edges are so sharp, they would rub themselves dull on the hollow side of the edge. To keep this from happening, a hone line is ground in the hollow along the edge. The hone line is a thin flat line that can be seen on the hollow side of the edge that runs from the tip of the scissor to the back.
A beveled edge, also known as a German edge, blade is a lot more durable than the other two types of edge. They are long lasting and is most likely the oldest blade design. The cutting edge is still very sharp, but the angle of the edge allows for greater durability. A beveller edge usually requires one or both edges to be serrated, which holds the hair and prevents is from being pushed forward when cut. This type of edge is suitable for blunt cutting, but not for more advanced cutting techniques.
So, let’s move forward with the most popular type of shears for a Barber
Haircutting shears are the most basic and common cutting tool you can see at any barbershop or salon. It's a straightforward pair of cutting shears use to remove hair for further styling.
one thing that sets haircutting shears apart from other haircutting tools is how it slices the hair. unlike other shears o scissors, this one can be used without folding or bending the hair.
It's extremely sharp and will cut hair like butter. These shears come handy for blunt and straight cuts with no layering or texturizing needed.
Another widely used haircutting tool is the texturizing shears. These have a design similar to scissors, but one blade has teeth that grab the hair. It can have 7 to 16 teeth and considered a special type of shears. This is used for thinning bulky hair without necessarily removing length.
Remember that texturizing shears aren't appropriate in removing length and it's not an all-around tool. You should only use this when you need to reduce the weight of a cut or to balance the haircut.
These are designed with different handle configurations than traditional, right-handed ones. The handles are contoured to suit the left hand for easier and more convenient cutting.
These Shears will create the opposite angle pressure to fit the correct force produced from a let handed user.
Thinning scissors are often interchanged with texturizing shears, despite being a different tool. Unlike texturizing scissors with widely gapped teeth, thinning shears have denser teeth. This is used to remove bulk while blending with the demarcation lines made by a pair of scissors.
Like texturizing shears, thinning shears are used to remove weight and thickness on the hair. But the difference is that thinning shears will help soften lines and blend sections. Also, thinning scissors can have as much as 25 or so teeth on one of its blades.
Basically, thinning shears will only cut half of the grabbed
Swivel Shears, on the other hand, are used to reduce the tension on the hands and wrist of the user. It's suitable for those suffering from carpal tunnel syndrome and repetitive strain injury.
Unlike other scissors, the swivel shears have a rotating thumb hole attached to the blade. Most of the time, the thumb is shorter and angled for convenient and more natural movements.
