Therefore, you need to know how to open a tin can without an opener. Using neat, uniform punctures is safer than cutting the cap. The method requires the use of a certain force.

For the production of metal cans, thin alloys are used. They are easily destroyed by solid objects. A stone or a piece of concrete is suitable for this. The main thing is that they have a rough surface. The process involves the following actions:

  1. Turn the jar upside down
  2. Proceed to rub the cover against the surface of the stone. Dishes are constantly checked for integrity,

  2. The spoon goes between the metal lid and the wall of the can,
  3. Reciprocating movements are performed. They are made until a small hole appears on the surface,
  4. Manipulations are performed along the circumference,
  5. As soon as a small hole forms, you need to expand it with a spoon to the maximum,

  1. Make a deflection on its lateral edge - push it with your fingers so that the lateral side is concave in the middle,
  2. Visually divide the side surface into 3 equal parts and make a second dent, which will become the second face of your isosceles triangle,

  4. As a result of your actions, the tin will burst on the folds and you will see what is in the middle,
  5. Another couple of such manipulations and you will open the jar completely like a mail envelope.

Pocket knife

In the presence of a small pocket knife, the task is simplified at times:

  1. Place it on a stable surface, preferably waist to waist,
  2. Place the end of the knife vertically above the inner edge of the lid, tightly fix it in your hand so that your fingers do not come off the blade, with the back of your hand up and make a hole,
  3. Move the tip sideways a couple of centimeters and similarly punch another hole, make similar incisions around the entire circumference and your treat will be almost open (Figure 4),

With a chef knife

  2. Put the container on something stable, waist-high, never kneel down - do not try to squeeze it between your legs,
  3. Grasp the knife at the intersection of the blade and the handle - the upper part is in the palm of the hand above it, the fingers lie on the sides of the handle, at a safe distance from the tip,
  4. Put the heel of the knife, the widest place of the blade, opposite its end, above the inner edge of the dishes near the side,
  5. Press it firmly against the lid to make a small hole in the puncture site (Figure 6),
  6. If it didn’t work out for you, get up and repeat the action, leaning on the can, holding the tool in one hand and pressing the other side with the other,
  7. Slide a sharp object along the edge a couple of centimeters and make a new hole, continuing around the entire perimeter as if you are wielding with a regular key,

  3. With force, press and rub the closed stew on the stone until the liquid becomes visible,
  4. Do not overdo it so as not to spoil the contents,
  5. Do not wash the tin completely - it must become thin so that it can be pierced,
  6. Insert a pocket knife or a screwdriver, any other pointed clean object and pry off the cover near the edge, carefully bend it and break it off,
  7. If there is nothing like this at hand, then punch the metal top inside the can with another stone, which will not be a good idea, since stone crumbs or dirt can get into the stew.
