With the help of a stone
What to do if you find yourself far from civilization and there is no knife, and no strong male hand either? Then be smart and try to open the condensed milk using stone or concrete. The technical process of production sealing of cans at the enterprise consists of bending the edges of the lid using a powerful press around the cylinder of its base. If you try to remove the top layer of metal that protrudes, then the tin container will open with ease. To do this, you need to perform a simple operation.
- place the bottom of the jar on your palm
- Press the jar with the lid down onto the stone or concrete and make movements in a circle
- After a couple of minutes, the edges of the side will be erased; lightly press on the sides of the lid and it will open easily.
Using a tablespoon
If you don’t have an opener at home, but you urgently need to open a can of condensed milk, what should you do? You can, of course, go to your neighbors, or you can use a simple method to open a tin container using a regular spoon. The process itself is a bit complicated and will take a lot of time.
- put condensed milk on the table, grab it tightly with one hand, and take a spoon with the other
- in the place where the jar is in close contact with the side of the lid, rub diligently with the edge of a spoon along the entire perimeter

Safety precautions when opening a can without an opener
All actions associated with opening a tin container without a special device carry the risk of getting a cut or abrasion. Therefore, when using available means, you should follow safety precautions so as not to cause harm to health.
Do not open a tin can with a knife while placing it on your knees or holding it between them.
To protect your hands from cuts, you can protect them by wearing thick gloves or wrapping them with cloth.
If you still cannot avoid a cut, you need to wash the wound with running water, treat it with an antiseptic, apply a gauze bandage or stick on a bactericidal patch.
Thus, using some techniques and devices, you can open cans even if a special knife is not available. However, when going on a hike or picnic, you should take a can key with you. This device will not take up much space and will help avoid injuries and waste of extra time.

The very first canned foods were made in the eighteenth century for army food. The container for them was large, heavy, and for a long time various tools were used to open it - a hammer, chisel, bayonet, chisel, and sometimes guns.
The first can openers were invented only in the nineteenth century. They were difficult, inconvenient and very rare. Since then, their design has undergone various changes. By the mid-twentieth century, the can opener had acquired its final form and retained its shape.
Types of can openers
Modern openers are one of the most necessary working tools in any kitchen. Working with them does not require special knowledge and skills. The main thing is to ensure that the can opener remains sharp at all times. It will be difficult to cut through the metal layer and open canned food with a blunt instrument.
Modern models differ from simple can openers in a more complex mechanism, shape, and blade length. Devices designed for easy and quick opening of cans are equipped with various additions: wheels, magnets, motors and handles. These models meet the most modern hygienic requirements. Thanks to the modern design, the metal of the opener does not come into contact with the contents of the can. When opening, you can be sure that metal particles or microorganisms will not get on the food. To work with can openers effectively, you need to know the features of various models and choose the right one.

Features and purpose
In the first half of the 20th century, the manual can opener was improved, and the useful invention became extremely easy to use. Since then, little has changed: despite the presence of several modern varieties of this instrument, the design still involves the presence of a handle and an iron plate, often made in the shape of a horn. Sometimes there are two such plates - for convenient opening of cans of any size, as well as bottles, homemade sealers. The design of the knife may also include the presence of gears. This opener is universal, it is also suitable for any diameter of cans, and does not form torn nicks on the rim.
Modern can openers are indispensable assistants for every housewife, designed for everyday household needs. This type of tool is significantly different from its conventional kitchen counterpart. First of all, the shape and size of the blade. Specialized, more complex knives, which are designed for easy and quick opening of containers, have a number of additional parts: handles, wheels, motors, magnets. A characteristic feature of modern products is a special operating mechanism that ensures there is no contact with the contents of the jar. You can be sure that microscopic metal particles will not get into your food.
Some models of can openers provide the ability to customize the tool for a specific user, based on whether he is right-handed or left-handed.
Depending on priorities and capabilities, each housewife will be able to choose a suitable device for opening cans. Modern industry provides a wide choice. All types of products can be divided into 4 groups. Each of them has its own distinctive features, and how to use the can opener will directly depend on them.
Manual
Manual canning knives are durable. This is a classic of the genre and the simplest representative of such products. There are the most primitive designs with a wooden handle, which were familiar to our ancestors. The product looks quite simple: an opening device is attached to a loop-shaped stop. On one side there is a blade for uncorking canned food, on the other there is a small hook for removing metal lids from glass jars. The internal part is fixed in a handle made of wood, rubber, sometimes plastic or metal.

There is a second design - with a wheel, it is safer and at first glance no less simple. However, this is not quite true. The operating principle is based on the rotation of the cutting tooth, which is ensured by pressing special levers.
Mechanical
Mechanical knives are more complex. Such devices are used by the catering industry. The principle of operation is that it pierces the surface from above, is attached to the side, and then, using a valve turned by the user, gradually opens the lid. A professional knife with a load of 30 or more cans per day is usually made of high quality steel and is rigidly fixed to the table using a clamp or through screws. It is capable of uncorking any type of canning containers at a speed of 5 pieces per minute.
Distinctive features of a mechanical knife:
- durable melanite shaft that does not corrode;
- high-carbon hardened steel blades, sharpened on both sides;
- plastic bushing, thanks to which physical effort is reduced when turning;
- convenient and quick disassembly, without the use of additional tools;
- Dishwasher safe.
This option is one of the most universal; every lover of home canning should definitely have such a device.
Automatic
This knife model is fast and easy to use. Runs on simple batteries. Simply attach the device to the lid and start the mechanism. Compared to its manual and mechanical counterparts, the knife has many advantages:
- ease of use - there is no need to make an effort to open the jar;
- safety – the edges remain smooth, eliminating the possibility of cuts;
- compactness - does not take up much space;
- the presence of a special magnet that prevents the opener from slipping and helps you easily remove the lid without getting your hands dirty;
- durability - even with regular use it can last for a long period of time.
Before using an automatic can opener, you must read the instructions. You need to be careful with the can opener if children are around. Do not open cans with high pressure (such as an aerosol can). It is also not recommended to open containers containing flammable liquids. When replacing the battery, you need to wait until the motor stops completely. Before cleaning the device, the batteries must be removed to eliminate the risk of spontaneous activation.
Electrical
The first device of this type was developed on the basis of a manual analogue with a cutting wheel. An electric can opener allows you to uncork containers as quickly as possible. Inside there is an electric motor, a knife mechanism, and a can lock. There are some differences in design, but the operating principle is the same:
- a special holder secures the jar;
- the user triggers a mechanism that uncorks the container;
- After opening the can, it is necessary to remove it from the latch.
Modern industry offers portable and tabletop electrical appliances. The first type runs on batteries. It is appropriate to take it with you to the country, out of town, or on a hiking trip. The desktop model connects to the network. Specialized varieties are also produced (they are used to open tin cans or use them as a corkscrew for wine bottles) and multifunctional electric openers.
Before starting work, you should properly secure the cutting roller so as not to injure your hands with the sharp part.

What to look for when choosing a bottle opener
When purchasing you need to consider:
- The material from which the can opener is made.
- Simplicity of design and ease of use.
- Compactness and weight.
To choose the most correct and successful model of a can opener, you need to determine what types of cans or bottles the device will open. And also how often it will be used.
If you need a small and universal model that can be used to open iron cans, cans or bottles and used occasionally, then a manual opener would be the best choice. When choosing, you need to pay attention to quality. A good material for manufacturing would be stainless steel. The handle should be made of wood, plastic or rubber and firmly fixed. There should be no defects or roughness on it.
If you need an opener that can quickly and effortlessly open several cans, then a mechanical device will be the best choice. It is the most convenient and less dangerous. But when purchasing a mechanical opener, you must remember that you will need a separate device to open bottles.
When choosing an automatic device, the quality of the tool is important. The best models are made with a body made of metal or high-strength plastic. Automatic openers are convenient, reliable and durable. But we must remember about timely replacement of nutrients. When taking the device with you on a hike or to the country, you need to purchase an additional set of batteries.
Electric models are very convenient for frequent use. But they are not cheap, so before purchasing you need to carefully read the instructions and the warranty period.
How to open a tin can?
When using a manual can opener, hold the device by the handle with your working hand and make a small hole in the sealed lid. Then, without removing the blade, cut through the metal, moving the knife in a circle. In this case, the hook should serve as a stop for the blade. Having completed the circle, lift the cut part with the sharp end.

To open a tin can with a mechanical can opener, you need to use the blade to pierce the metal from the top. The device is attached to the side on the side, rotates and gradually opens the can when you turn a special twister by hand. With this tool you can handle a lot of cans.
The automatic machine operates using ordinary inexpensive batteries. To work, you need to attach the device to the top of the canned food and turn it on by pressing the button. Before using the automatic opener, you must carefully read the instructions. It is strictly forbidden to open cans that are under high pressure, aerosols, or containers with flammable liquids.
Before working with an electric knife, carefully study the instructions for use. It is necessary to attach the cutting roller correctly to avoid cuts. And while opening, hold the container with one hand.
How to use a can opener
This item is a classic device for opening tin containers with preserved food. Handling it does not require special skills or special training. But you need to ensure that the blade of such a can opener always remains sharp. If the blade becomes dull, the device will not cut through the metal well and opening the container with its help will be problematic.
Ordinary
An ordinary can opener is a simple invention consisting of a wooden or plastic handle, at the end of which a metal knife sharpened on one side and a metal loop are attached.
When using this device, you need to hold the handle with your right hand and use the sharp tip to make a small hole in it.
Then you need to move in a circle, cutting through the tin lid. The steel loop should rest against the edge of the container. You can lift the cover by lifting it with the sharp edge of the key.
With wheel
Wheeled knives are two metal handles joined together. A round wheel is attached to one of the edges of these handles, acting as a knife, the edges of which are sharpened.
Opening a can with a wheeled can opener is quick and easy. To do this, you need to hold the edge of the can between two handles with one hand. And the second is to turn the handle, which drives the cutting wheel.
Moving in a circle like this, the container is easy to open.
This opener is safe to use and requires less effort when opening compared to a regular one. But when using it, you need to constantly turn the container with canned food and make sure that it does not tip over.
