It happens: Suddenly there is no can opener to open the ravioli. When camping, but also in your own home, it just happens that the important can opener has disappeared. Then good advice is expensive and the box must be opened despite all odds. How this works, we show and explain here.

Everything is packed for the weekend trip. Tent, mattresses, camping stove and since no fridge can be taken, of course, canned food. At the finish, small but important details are missing: can opener and corkscrew. How annoying, because usually in such situations certainly no household shop nearby that sells these things at sunset. The outdoor fan knows his way around and knows how to open the tin without the necessary tools and save the dinner for the group.

Despite missing can opener open a can

The problem: The can opener is missing! If the most important tool is missing to open a can, not much can be prepared or prepared. Here creativity and a little skill is required. There are certainly adventurous ways to open a metal can with a knife. Anyone who knows the large cuts that may arise, is only too happy to do without it. We do not recommend the option of opening a can with a sharp knife in our DIY guide. For one reason: The risk of deep cuts is too great and there are actually better options. Another side effect, about which no outdoor fan is happy: Even the blades of expensive knives are out of focus with this method. Other options, such as the screwdriver, which is hit with the ball of the hand into the can, we advise against the high risk of injury.

Caution, danger of injury

Material and preparation

The fact that a can is a tinplate or aluminum, which is relatively soft compared to other types of metal and therefore can be processed or opened well, is certainly interesting. This fact is the basis for opening a can without an opener. Furthermore, the construction of the can itself contains the sought-after solution. These are the outer wall and the lid and bottom, which simply overlap on this outer wall. So a smooth, rough surface of concrete is needed. The footpath in town, path plates in the garden or a simple stone are now needed. The smooth surface is necessary, it should be as straight as possible. Anyone who does not find such a smooth surface in the middle of nature, will find the latest in the next village: The pedestrian zone, wherever there is a street, there is also the required area to open the box.

You need this:

  • Your can
  • a straight area of ​​stone, for example a stone or the footpath

Tip: drive to the next village or go to the entrance of a shop or restaurant. At the latest here you will find the required rubbing surface.

Open the can

The can is now rubbed with light pressure on the stone back and forth. Thanks to the friction slowly opens the edge of the protruding edge. Depending on the condition of the can, it takes around 20 - 30 seconds for the first hole to appear at the edge of the edge. After further rubbing loosens the mechanically patched edge, the lid can then be carefully pressed into the can and then removed. Beware of small metal shavings that may have arisen during rubbing.
