Manual Can Opener

This is the first type. As you can see from the picture, the manual can opener contains two arms and a rotatable handle to manage it. 

Most of you may not recognize, most manual can openers look familiar; however, their operating principles fall into two categories. The can opener either slices the lid of the can inside the can rim or expunged the can’s outside edge. 

The first method will help hold the lid on and use it to hold the food in position when removing the liquid. In contrast, the second one will enable the lid to be put on a can for storage purposes. However, you need to be careful not to grab the can from the top; otherwise, you will make such a messy mess. 

Electrical Can Opener

This is the second type, and most families choose to buy it. 

As you see from the picture, you will realize that it contains a magnet lid that will keep the lid from falling into the can. Moreover, the blade will be made from durable, sturdy materials like stainless steel to increase durability. Also, height is the fundamental factor you need to consider because it has to be tall enough for your highest cans. There is also a removable lever for quick cleaning. 

Furthermore, some additional features that will assist you in opening the can are the automatic shut-off so that you won’t have to control the cutting process and so much more. 

Now, we think you all have a typical picture about the can opener; we will move to the part where we will discuss the benefits and drawbacks of each kind so that you can fully understand them.

As you can see, most manual can openers come in a compact size; therefore, it is easy to store in limited spaces, such as a kitchen drawer. We are sure that people with occupied kitchen countertops will appreciate this feature. 

User-friendly

Since the opener only requires the human’s energy; therefore, you don’t have to worry that you may have to spend time learning to use the opener like the electric one. Moreover, since it doesn’t need electricity, you can freely bring it anywhere you want without hesitating that it will unexpectedly run out of electricity and become useless. 

Although most electric models are battery-powered; however, it still causes you trouble when the battery dies, and you may not carry extra batteries. 

Disadvantages

It May Take Longer To Open The Can

Since it only needs human energy, this is precisely not suitable for people who suffer from serious health issues that are hard to use their hands or experience poor hand sturdiness. These people will have difficulties using a manual can opener because it needs strong force from the hand; consequently, they may hurt themselves. Therefore, an electric can opener will be a better option for them. 

Dangerous

The manual can opener contains sensitive components, such as the blade. If you are not careful, you may cut your hand on the edge while putting strong force from your hand to the opener. Most manual can openers are not dishwasher safe; therefore, you may cut your hand when cleaning them. This feature is even more dangerous for your children if they accidentally touch the sharp blade.

Youngsters may not allow using this opener, but teens or adolescents can use it. That’s why we said that it is appropriate for almost everyone.

Fewer Injuries

As you know, all you have to do is press a button, and the machine will do the rest of the task for you. Therefore, you are less likely to hurt yourself, unlike the manual model. 

Moreover, with the electrical model, you only have to unplug the cord and wash it with water. With sensitive parts like the blade, you will have a toothbrush to eliminate the dust and debris—no need to worry that you may accidentally cut your hand. 

Disadvantages

You May Spend More Time To Learn How To Use

Like any equipment, with an electric can opener, you will have to learn how to use it. Although some models include only basic features, you still have to spend time to get to know the machine. With the manual model, you can just grab and use it right away!

Electricity Could Be A Problem 

You may argue that most models now use batteries; however, if your opener loses batteries and there is no battery around you, the opener will become useless. The situation can be worse if your machine uses an electrical outlet. Not every place you come will have an electric socket; therefore, a manual may be more suitable if you are away. 

Now, you may develop some basic knowledge about the can opener, what it looks like, and when it is suitable, you will know which model you should buy. Therefore, we will head to this article’s essential topic: how to sharpen a can opener. Firstly, you need to know when it is the right time to point it. This process is the same between these two types, so you should not worry if we don’t split it into two parts. 

Signs That Your Can Opener Needs To Get Sharpened

The most foreseeable sign you can see that when it stops working. You may ask yourself, when does it stop working? It is when you use strong force from your hand, but suddenly, your hand slips, and the lid still stays the same. Moreover, you will realize when it takes more time to cut the cans’ tops as usual. This is the time you should sharpen your can opener. 

Moreover, there will be a time when the can opener’s blade requires replacement because right now, sharpening is no longer helpful to the edge, and it has rust everywhere. 

Some Methods To Sharpen Your Can Opener

Cleaning

This method is the easiest one, and we highly recommend you to do it right after finishing using the can opener. 

All you have to do is unplug the cord and clean it with water. You need to make sure that all specks of dirt, debris, and food particles are eliminated from the can opener. Once a month, we suggest you soak the blade into warm water with soap or not; this is up to you. You may wonder why you have to have to do this. 

The answer that proper cleaning will extend your can opener’s durability. For your information, sometimes, during the cleaning process, you may neglect detailed cleaning. For example, instead of using a toothbrush to remove the edges’ particles, you simply let the water flow and do not scrub. 

In the short-term, you still see the opener shines; however, many particles stick into the edge through time, and you may never eliminate them. That’s the main reason why your blade is dull. 

In general, you have to use the toothbrush to clean the blade, and once a month, you should soak it in warm water. 

Use Aluminum Foil

This method is recommended by most people when you have tried almost all the ways to sharpen your blade, but it is not working. 

Now, we will show you the ways to do it.

Firstly, you will need a little aluminum foil and fold it in half or even in fourth to thicken. This depends on your choice about the thickness level. 

Secondly, you will carefully run the aluminum foil over the blade to sharpen it. After that, you will rotate the blade in different directions to entirely point every blades’ sides. Make sure to carefully run the edge through all the aluminum foil’s length. 

This may be hard for you to imagine; therefore, we have included the video of how to sharpen a scissor using aluminum foil. The first step is identical; the difference is that you have to run the aluminum foil over the blade, not just cut it like the scissor. 

After that, you should check if the edges are sharp. If not, repeat the steps until you see the results.

Use Sandpaper

If you don’t like the aluminum foil method, you can just use sandpaper. We will simply have to repeat the same steps as the aluminum foil. 

Firstly, you will need a piece of sandpaper, with the sandpaper, we think you only need to fold twice. 

Next, you will carefully run the sandpaper over the blade in every possible direction by modifying the handle. Then, if the edge is sharp, your task is done. However, if it is not, you can simply repeat the process until you see the results. 

For your information, both aluminum foil and sandpaper are valuable materials to clean your blade and make it sharpen again. 

Use The Knife Or Scissor Sharpener

This method is beneficial for an electric can opener since you will have difficulties using aluminum foil or sandpaper. Instead, let’s follow these steps.

Firstly, make sure that you unplug your opener from the electric socket or temporarily remove the battery for safety reasons. 

Secondly, you should wash and dry the knife sharpener. If you use it regularly, you may pass this step and move to the next part. 

Next, you will support the can opener’s body and put the knife sharpener inside. For convenience, make sure that the sharpener is on your right side. 

Press down the lever, then place the blade on either right or left sharpener’s side. 

You only have to run the sharpener over the blade’s total length, with slow, steady motion in this step. You need to remember two points: you need to run the sharpener in the blade’s full size and a controlled movement. 

Repeat the step 5 to 6 times and then change the side. You should stop when it reaches the sharpness level you want. 

Finally, you should clean and dry your sharpener blade. You should be cautious when cleaning the knife to prevent you from hurting yourself. Just one more point, you need to use this tool at the solid surface for effectiveness. 

For better understanding, this video could be a big help to you. Although it refers to a scissor or a knife, the technique is almost the same.
