Take a large pair of scissors or shears in your hands, which you hold
out, palms upwards. Hang them by their rings on the little fingers.
Close the hands with a slight inclination towards the scissors, so that
the finger tips only are in the rings, and the blade is supported on the
inner fleshy part of the palms.
As you turn your closed hands, the scissors will turn, and on bringing
the knuckles upward the point will be forward, and you can open and shut
them freely.
