The second scissor blade is provided with a tooth against the horizontal surface of which the Eccentric arms act in such a way that the scissors are opened when one of the arms is lowered in order to immediately closed afterwards by the action of a spiral or other spring to become as soon as the arm leaves the horizontal surface.

This way all the grass or other material that is between the leaves will be the scissors lies, instantly cut through.
