Adjusting Scissor Tension Or Balance
This is often called “the fall” and refers to how far a held blade will fall when released from a horizontal position.
Hold the scissor with your left hand and the tips pointed straight up.
With your right hand open the scissor blades so they open about 45 degrees.
Release the blade in your right hand. The released blade should fall enough that the tips have a slight gap between the tips of about 1/4 inch. If the scissor closes completely with the tips aligned, the scissor is too loose and the tightening screw should be adjusted a bit clockwise. If the tips are farther than 1/4 inch apart, loosen the screw a bit counter-clockwise.
