Technology for opening a can with a tablespoon
Hold the spoon in the palm of your right hand; it should be dry and clean, otherwise it will be very difficult to hold it in a stationary position. Hold it in such a way that the end about 2-3 cm long remains free.
With your left hand, grab the tin can, and with the tip of the spoon, begin to rub it on the lid of the can. You will have to make significant efforts, calculate your strength. The amplitude is approximately 2–3 cm. First, the lid will bend and a groove will form, this will make the work a little easier - the tip of the spoon will not slide to the sides.
Continue rubbing until a through hole appears.
Insert the tip of a spoon into it and press it firmly while simultaneously moving towards cutting the can.Make rocking movements, now the edge of the spoon should not rub the edge of the metal, but when moving from top to bottom, tear it apart. The thickness of sheet steel for cans varies within 0.20 mm; it breaks even under medium loads.
Continue cutting the lid in a circle; you don't have to try to make the cut perfectly straight. The spoon should always be vertical and tightly clamped; slipping during cutting is strictly not allowed. When 1–2 cm of metal remains intact, use a spoon to lift the lid and bend it upward. That's it, the jar is open, the contents can be taken out without any problems.
But you must remove it from there carefully; the edges of the lid have sharp jagged edges and can easily injure your hand.
