Which electric pencil sharpener is best?

Given how much time people spend on their smartphones, laptops and tablets these days, it probably doesn’t seem like there’s much need for pencils. But whether you’re a teacher, student or artist, pencils can still come in handy. With an electric pencil sharpener, you can be sure your pencils are always sharp and ready for writing or sketching.

Electric pencil sharpeners may seem the same, but they can differ in how they run, the speed they operate and how they collect their shavings. If you’re in the market for a durable, heavy-duty electric sharpener, the X-Acto ProX Classroom Electric Pencil Sharpener is an excellent option.

What to know before you buy an electric pencil sharpener

Power source

Models that run on batteries are compact and don’t have any cord to get in the way, making them highly portable. They don’t have as much power as a corded sharpener, though, so they can take a little more time to get your pencils as sharp as you’d like.

Corded electric pencil sharpeners require an outlet or a USB port for operation, so they’re not as portable. However, they have a more efficient motor and more power behind them, allowing them to sharpen more quickly. You also don’t have to worry about replacing batteries.


The main benefit of an electric pencil sharpener is how fast it can sharpen your pencils, so they all operate pretty quickly. Still, there’s some difference among models in their speed.

If you’re buying an electric sharpener for a classroom, you’ll want a heavy-duty or professional model so it can handle many pencils in a short period.

Pencil size

While most pencils are a standard size, there’s some variation among sizes. You want to choose an electric pencil sharpener that can fit the pencils you use most often. Traditional pencils have an 8-mm diameter, but you can find some up to 10.5 mm in diameter.

To make sure you can sharpen any size pencil, look for an electric pencil sharpener with an adjustable wheel. You can choose the opening size based on the diameter of your pencil so that you can sharpen multiple sizes. Adjustable electric pencil sharpeners can offer up to six size options, making them an excellent option for a classroom.

What to look for in a quality electric pencil sharpener

Shavings receptacle

Every electric pencil sharpener features a built-in receptacle that collects the shavings from the pencils during sharpening. Many sharpeners stop sharpening once the receptacle is full, so you have to empty it from time to time.

If you choose a model with a larger receptacle, though, you won’t have to empty it as often. Instead, look for a sharpener with a well-sized shavings bin, especially if you want to use it in a classroom or another setting where multiple people will use it.

Sharpening angle

You can find some electric pencil sharpeners that let you change the sharpening angle. Adjusting the angle helps ensure that your pencils are as sharp as you’d like. It can also help prevent the lead from breaking during sharpening.

A larger sharpening angle typically exposes more of the pencil’s lead, which can cause breakage. A smaller angle is usually more effective at keeping the lead from breaking, although it won’t get your pencils as sharp.

Blade replacement

If you use your electric sharpener regularly, its blade will wear down over time. A dull blade can cause your pencils to splinter and the lead inside to break. Some electric pencil sharpeners let you replace the blade, so you can keep using the sharpener even when the blade wears down. Unfortunately, other models don’t allow for blade replacement, so you have to buy a new sharpener when the blade dulls.


All electric pencil sharpeners make some noise when used, but it can be disruptive if the sharpener is extremely loud. In a classroom, it helps to choose a model that makes as little noise as possible. Because they have a highly efficient motor and nonskid rubber fit, they don’t vibrate as much, reducing the noise they make.

How much you can expect to spend on an electric pencil sharpener

You’ll usually pay $6-$95 for an electric pencil sharpener. Battery-operated models that aren’t adjustable range from $6 to $18, but corded models generally cost $15-$36. Plug-in models that are adjustable have a large shaving receptacle and don’t make much noise can cost as much as $95.
