What is the primary purpose of the tension screw on shears?

To adjust the cutting angle
To control the cutting distance
To regulate the blade movement
To secure the blade in place

The correct answer is: To regulate the blade movement

The primary purpose of the tension screw on shears is to regulate the blade movement. This tension screw allows the barber or stylist to adjust how tightly or loosely the blades are connected, which directly affects how smooth and precise the cutting action is. When the tension is set correctly, it ensures that the blades move together effectively while cutting, allowing for clean and accurate cuts. If the tension is too loose, the blades may not align properly, leading to uneven cuts, whereas if it is too tight, the shears may be difficult to operate and could cause fatigue. Understanding the role of the tension screw is essential for maintaining the performance of the shears and providing quality haircuts. This adjustment enables barbers to customize the functionality of the shears to their specific cutting style or technique.
