What is Scissor?

A scissor is a cutting tool for cutting cloths, paper, hair, metal sheets, ropes, & wires. It is made of two sharpened blades pivoted at the center. Due to the pivot point, these two sharp blades can slide against each other by applying force from the thumb and finger on two bows. Scissor is used in a wide variety of applications in barbershops, sheet metal workshops, gardening applications, kitchens, cloth-making, and more. Due to its wide applications, it is made with good material to achieve better strength and cutting properties. Let’s look at the parts of scissors and their functions.

Scissors Parts and Functions

Points or Tips

It is the end of the blade. It forms when the scissor is in a closed position. 

Finger Bows

A Finger bow is a portion where the user can insert his/her finger to use a scissor. Thumbs and fingers are two types of finger bows.

In the thumb, the bow user can insert his/her thumb, and in the finger, the bow user can insert his/her finger. The finger can be the middle or forefinger, or it can be as per his/her comfort.


Blades are metallic plates with an aesthetic shape for better strength and a good look. There are two types of blades- the inside blade and the outside blade. 


It is a dull and non-sharpen edge of the inside and outside blade.


Inside and outside blades have an edge. Edges of the scissors have 3 different types.

  • Serrated Edge- This is suitable for beginners because this edge slips less and gives more control when cutting dry hair. 
  • Straight Edge- It is ideal for slice and point cutting. 
  • Convex Edge- These edges are suitable for smooth cutting. Most professional barbers use convex-edge scissors.

Adjustment Screw

The adjustment screw is for connecting the inside and outside blades in the middle. In the middle, there is a hole in both blades to insert a screw for clamping. It can be adjustable or non-adjustable.

With an adjustable screw, we can adjust the tension in the blades as per requirement. At the same time, the non-adjustable screw is to connect both the blades. 

Bumper or Stopper

The bumper or thumb bow is attached to the inside bow. When the scissor is in the closed position, the bumper or stopper touches the finger or outside bow. 

Finger Rest

Finger rest is metallic support given to the fingers. It can be removable. While cutting hair, sometimes the barber uses a finger rest to support and get a good grip during hair cutting.


The purpose of the shank is to connect the finger bow to the blades.


The wing is the flat portion in the area of the adjustment screw. On the wing, there is a hole for the adjustment screw. 

Outside Ring and Inside Ring

The inside part of the finger bow or outside bow is called an outside ring & the inside part of the thumb bow or inside the bow is called an inside ring.

Ring Flat

It is the surface of the bow.


The Joint is the portion where two blades connect with an adjustment screw. 


It is a manufacturer symbol on the flat surface of the wing. Below the logo, some basic information is given, such as material, model number, size, total length, and more.
