How to Adjust the Blade Tension of Your Hair Shears

December 13, 2019

It is extremely important to know how to adjust blade tension to ensure maximum performance and extend blade durability.

If the blade tension is too loose, it will allow the shears to fold the hair. If it is too tight, it will cause unnecessary wear and user fatigue.

To test the tension on your shears, hold the shears with the tension knob facing you and the thumb handle in your left hand.

With the shears perfectly straight, lift up on the ring finger handle to open the blades halfway and then let the ring finger handle go.

The blades should close two thirds of the way from the tip back.

You should have a 1" to 2" gap between the blade tips.

To tighten the tension, turn the adjustment knob to the right.

To loosen the tension, turn the adjustment knob to the left.

If they are still closing all the way, repeat the steps until there is a 1" to 2" gap between the blade tips.

If the shears hang open too much, loosen the adjustment knob until the proper gap is achieved.
