As an educator, student or drafting professional, the last thing you want is to have a bunch of pencils that have gone dull. It can be a frustration and a hassle.

It’s important to make sure you have a high-quality pencil sharpener so you can get back to work without delay. As a common problem, most students still come to class without one or have their own sharpener that’s simply ineffective.

Manual pencil sharpeners are hard to use and can create more of a mess than they’re good for. Also, gripping the pencil to use a manual sharpener can often end up breaking the lead within.

It’s why so many teachers have decided to invest in a high-quality pencil sharpener that the entire class can use. However, at-home or consumer grade devices are not going to stand up to the wear and tear of a busy classroom environment. Students tend to be rough with equipment which can dull a low-quality sharpener in a short amount of time, costing more headache in the long run.

When it comes to the classroom, educators are better off investing in a heavy-duty electric pencil sharpener that’s available to everyone. Heavy-duty electric sharpeners won’t need to be replaced as often. Ultimately, they save issues and get the job done faster. From the quality of their components to their warranty, choosing a heavy-duty sharpener is a superior option.

While we’re placing a huge emphasis on how great they are in classroom settings, there are a growing number of people that are choosing to purchase one for their homes as well. Believe it or not, there are over a hundred options when it comes to choose from. The amount of products can be overwhelming to sift through. To help make the process easier, we’ve compiled this in-depth article on the best heavy duty pencil sharpeners currently available.

How We Selected the Best Heavy-Duty Electric Pencil Sharpeners

After polling a selection of teachers, students and professionals that use pencils regularly, our team evaluated dozens of options to come up with the list below. While there are different types of sharpeners on this list, they all embody most, if not all the following criteria.

  • Build Quality: Sturdy components are good but how they’re put together is crucial. Many of the sharpeners we examined had good components, but were assembled poorly, which translated to poor overall quality. The products featured in this article come from brands that have demonstrated a commitment to quality craftsmanship.
  • Durability and Longevity: We sifted through dozens of user reviews that included long-term feedback. A main purpose of a heavy duty electric pencil sharpener is for it to last. We made sure that we included options that stood the test of time in real-world situations.
  • Output: Not all units are capable of the same quality sharpening. We looked for sharpeners that got the job done with minimal fidgeting on our end.
  • Capacity: Sharpening a pencil can produce a tremendous amount of waste. We took into account the amount of shavings each device could hold to reduce the number of trips to the wastebasket.

When it comes to the Westcott, the sharpening blade itself is a thing of beauty. It’s an extremely efficient helical 10-blade sharpener that produces an incredible tip. Running it through dozens of pencils, the consistent results impressed our team every single time. Another thing you’ll notice is that it’s much quieter than traditional consumer-grade electric pencil sharpeners. The number of blades are much more efficient at grinding, resulting in less noise.

The Bostitch Office QuietSharp came in as a close second to the Westcott. The iPoint got the slight edge due to the tremendous track record Westcott has in this industry. Also, because it was slightly easier to use for younger people. That said, the QuietSharp is an incredible pencil sharpener that exceeds all other sharpeners in a variety of ways.

With an average sharpening time of less than 4 seconds, the Bostitch is one of the fastest on the market. In fact, it’s over 70% faster at sharpening compared to most other options.

It comes with the name “QuietSharp” honestly. This sharpener is incredibly quiet due to its proprietary “quiet” mechanism. It allows for continuous operation at low volumes to limit distractions.

Bostitch’s quiet noise operation goes beyond pure volume. Somehow they were able to optimize the blades to sharpen while producing noise that was lower in pitch than the traditional high squealing characteristic of other sharpeners. The result is, the majority of the noise blends into the background more easily.

The size adjustment dial is very smooth while staying in place during sharpening. Internally, the dual ultra helical steel cutter blades did a fantastic job producing a high-quality pencil tip over and over again.

This machine sharpens extremely fast. We were able to take a dull pencil to full sharpness in less than two seconds. We want to point out that the extra power of this unit does increases the amount of noise. It may not be a big deal for some but it’s worth pointing out.

The AFMAT comes with non-slip feet which fixes an issue that a lot of sharpeners have of moving all over the table when in use. We found that they formed a slight suction effect, which provides excellent stability.

Looking at the inside, the AFMAT comes with an industrial-grade helical blade that’s rated to last for up to 7,000 cycles. This is dramatically higher than most sharpeners which are rated for only a quarter of that. In some third-party tests, the motor and blade in the AFMAT were able to sharpen 500 pencils continuously without stopping to cool down.

The high-capacity shavings bin is designed so you can easily see where the waste levels are before it becomes an issue.

Teachers love this unit because it includes some thoughtful safety features that make their jobs easier. A fly-away cutter prevents over sharpening by stopping the moment the pencil reaches its ideal sharpness. The SafeStart motor stops shaving if the waste bin is not in place. Ultimately, this greatly reduces the chance of injury.

Compatible with color pencils, it’s a great all-purpose sharpener that’s extremely durable. At this price point, it’s an ideal option for many people.

What to Consider When Choosing the Best Heavy Duty Pencil Sharpener

While none of these sharpeners will break the bank, choosing to buy a heavy-duty electric sharpener is still an investment. If you’re an educator, you want to make sure you’re choosing one that’ll serve your students the best. Keeping some of these considerations at the forefront of your mind may help.

  • Assess Your Current Needs: Gauging the average number of pencils that need to get sharpened on a weekly basis will give you a good baseline of what kind of sharpener you’ll need. If you’re needing to process more than thirty-five pencils per day, you may want to consider something like the LINKYO that can sharpen pencils in under two seconds.
  • Types of Pencils: You’ll want to make sure that the sharpener you choose will accommodate the size and kind of pencils you need sharpened.
  • Age of Users: If the majority of the users are going to be young, it might be a good idea to go with something that isn’t overpowered. But if it’s going to be used by adults, going all in on performance may be the best choice.
