In order to prepare for the winter and make conservation, you need not only a good recipe and vegetables, but also a high-quality sealing key, which ensures that the germs do not enter the jars before they are opened. In stores, there is a wide selection of seaming keys - from semi-automatic to fully automatic.
Instruction manual

When choosing a seaming key, consider the type of mechanism and the seaming method that will suit you in terms of convenience, quality and price. So, automatic keys are very easy to use and help to tighten the can in only half a minute: after putting the lid on the can, you put the key on top and press the lever several times. One of the most popular among housewives, a semi-automatic sealing key should be turned several times in a circle, however, if the neck of the can is uneven, such a key will not be able to tightly close the can with preservation. The snail key rolls up the jars a little longer, because after the rotation is complete, it needs to be twisted in the opposite direction. The advantage of such a key is the uniform pressing of the edges of the lid to the jar, as well as the fact that using this key you can perform the opposite operation - remove the lids from the jar.

One of the most reliable, but at the same time expensive, is a seaming key equipped with two rollers. Such a key with clamping devices fixes the can, by turning the screw and pressing the handles, bends the edges of the lid to the can, and then after a circular motion hermetically closes the container. Such a key will become your reliable assistant and will last for many years.

You can choose any of the listed seaming machines, but keep in mind the most important thing - the seaming key must be durable and of high quality, the handles must be rotated easily and effortlessly, and it is also convenient to lie in the palm of your hand.

Keep in mind that seaming keys with grooves are more suitable for women, since they require less physical effort when rolling. All sealed keys and machines equipped with special screws get tired very quickly.

You can check the quality of the seaming key as follows: after closing the can, inspect the lid, it should not have dents, tubercles or other irregularities. A flat lid tightly pressed to the jar is a guarantee that preservation will be successfully stored, and the key coped with its task.

Try to displace the cover: it should not change its position even with the most maximum efforts on your part. Also, turn the jar upside down: if bubbles rise from the lid or liquid leaks, therefore, the preservation is poorly closed and the key is very poor-quality. After that, repeat the procedure and tighten the jar again.
