What is a Can Opener?
Simply put, a can opener is one of the most commonly used kitchen tools or devices that help you cut into a metal can with great ease and convenience.
These can openers also operate in a fairly simple manner in which they puncture into the metal can and rip off or tear apart the top of the can in a single, swift motion.
Can Opener Materials
Most can openers are made out of metal with some plastic elements such as handles, bases, or levers. However, some can openers can have wooden or bamboo components depending on the model.
Different Types of Can Openers
Since there is such a huge variety of can openers, you need to have the best of the lot to help save time and energy. Here are some of the most common and popular types of can openers that you are likely to find in almost all households in today’s time.

This can opener is also often referred to as the “claw-type opener” particularly due to how it is shaped like a claw. Level type can opener is one of the most basic and primal types of can openers that has gained significant population over the years and is still used in several households.
This opener is one of the most foremost designs that were used to slice open cans. It comes with a large sickle-shaped blade that helps puncture the lid of the can and open it up.
On the very opposite side of this curve-shaped blade, you will notice a kind of a shield or guard that serves the purpose of keeping the blade from cutting too deep in the can. This prevents the blade from touching or contacting any contents inside the can.
The right way to use the lever type can opener is to puncture the rim of the can lid and then slowly drive the sickle-shaped blade into the can. Saw along the edges with caution since it can result in a very sharp-edged container.

This can opener often comes with a “key” or crank, as well as “tongs” which helps one turn the can. This allows the serrated wheel of the opener to easily open the can.
The correct way to use the butterfly can opener is to first puncture the lid with the sharp ‘church-key’ kind of a pointed end and then tightly secure it with the pliers of the can opener.
