How to find the best electric can opener with knife sharpener?

If you’re looking for a can opener with built-in knife sharpener, the options narrow down quickly.

However, there is still a decent range of models to choose from, and if you haven’t found what you’re looking for in our buying guide, we have a few pointers that we recommend you to look for if you decide to look at other models instead.

1. Durability

Most electric can openers and knife sharpeners are made with a plastic house and metal cutting parts, which in itself is a durable combination.

However, to ensure the best durability possible, you’ll have to look at the different parts. Are there any small parts that look like they could break off easily?

Does the product receive positive ratings for the overall build quality?

These are important things to look for, if you want the highest durability possible.

2. Safety

You wouldn’t want your new electric can opener to leave jagged edges on your cans, but you wouldn’t want it to accidentally switch on either.

Look for an electric can opener with a high safety rating as well as proper safety features, such as automatic shutoff, to minimize the risk of unexpected accidents.

3. Versatility

Cans don’t come in one shape. Some are tall, some have a larger diameter, and some are smaller than others.

Make sure you get an electric can opener that is capable of opening both large and small cans, otherwise you’ll end up opening some cans manually while your new electric can opener just sits there.

4. Cleaning

Some electric can openers have removable cutting units, and some of them are even dishwasher safe.

This allows you to easily prevent cross-contamination between multiple cans, as you can quickly detach the cutting unit and rinse it under running water.

For this reason we recommend that you opt for an electric can opener with removable cutting units.

5. Type of knife sharpener

One thing that you have to take note is that knife sharpeners in the modern world come in different types.

The one that usually comes with the electric can opener is just one of them. Here are three different types of knife sharpeners that you may want to look into:

  • Whetstones

Whetstones are the most basic one to have, the cheapest one but relatively harder one to use. It is also called oilstones or Japanese waterstones. These usually come in rectangular shapes with a gritty surface.

Instead of carving out a new edge on your knife, it just sharpens the existing edge that your knife has. You have to hold it in at a certain angle and run it down the stone a couple of times before you get the sharpness that you want. It may be a bit dangerous if you aren’t used to but it is definitely something to look into.

  • Manual sharpeners

The manual sharpener is the one that would often come with the electric can opener. It usually comes in a V-shaped notch where you’d pull a knife through to sharpen it. Unlike whetstones though, it carves out a new edge for your knife. But it is safer to use than a whetstone.

  • Electrical sharpeners

Electrical sharpeners get the job done easily and efficiently compared to manual sharpeners and whetstones with less effort on your part too. The angles are already set the right way so all you have to do is insert the knife in the notch and let the rotors and grit do its part on sharpening your knife.
