7 Best Sharpeners for Classroom Writing and Drawing

As you know, I’m passionate about the uses of technology in the classroom. One item that seems to be left out most of the time but has a major role in the classroom is the humble pencil sharpener. It comes in the simplest hand-held design to a high-tech electric machine. There may come a day when we are a paperless society, but it isn’t today, and our students still need to learn how to write on paper.

Trial and error is a significant part of learning at any age, but it’s vital for elementary school children. Hence, the pencil and eraser. Keeping all the pencils in your class sharp can require strategic thinking. One sharpener in a classroom often becomes the proverbial water cooler in an office and is a place children congregate to whisper and share gossip.

Best Sharpeners for Classroom

In the past, students are given a small plastic or aluminum sharpener, which half of them promptly lose. So they borrow their friend’s or ask the teacher. Both scenarios are disruptive to the class, so I conducted deep research to find a solution. Here I’m going to address this problem with recommendations of different types of pencil sharpeners and some classroom organizational suggestions.

For those of you who need a quick overview, here are my top three recommendations for different uses. Below, I give detailed descriptions of seven sharpeners including more details about these three.

My Top PickBostitch QuietSharp Glow Electric Pencil Sharpener

Bostitch EPS11HC

  • Replaceable cutter
  • Suitable for colored pencils
  • Regulates the timing for sharpening
  • Quiet

Best for: If you only get one pencil sharpener for your classroom, this is the one to get. It regulates the timing for sharpening a pencil, which is a great advantage in a classroom because the students tend to over-sharpen pencils or just continue grinding to waste time and talk to their friends waiting in line.

This is my top pick for several reasons, but the two main reasons are the blue light signifies the pencil is sharp, so children can’t stand there forever, and it’s quiet. This is important to me because some electric pencil sharpeners are so noisy they cut the concentration during a lesson.

Also GreatBostitch Metal Antimicrobial Manual Pencil Sharpener

Bostitch MPS1-BLK

  • Can be permanently screwed in place or held in place with a clamp
  • Accommodation for 8 pencil sizes
  • Tip saver prevents over-sharpening

Best for: This is a good pencil sharpener if you don’t want the sound of an electric sharpener in your classroom. I prefer the electric model because it is fast, provides a sharp point and I can control it, so the sound isn’t a problem.

Check price →

This is basically a traditional manual pencil sharpener with a few added features. The best part for classroom use is the ease of removing the blades and cleaning. This is important for sharpening colored pencils, and I don’t think there is any point (no pun intended) in having a pencil sharpener that has a problem with colored pencils in a classroom.

Also GreatPencil Sharpener with Switching Modes - Manual and Electric

Pencil Sharpener, Manual and Electric

  • Switches between electric and mechanical sharpening
  • With three blades
  • The body is durable
  • Sharpens very quickly

Best for: I recommend this for normal math or writing lessons but not for art projects.

This sharpener is small, portable and safe for a classroom of very young children who are still learning how to sharpen a pencil. It stops automatically when the pencil is sharp, so children can’t sharpen the pencil down to the end at one time. The shavings are easy to remove.

Why Are Electric Pencil Sharpeners so Useful?

Pencils, erasers and sharpeners are all an important part of a schoolchild’s life. Pencils and erasers are about the same as they have always been and don’t really need to be any different. But, pencil sharpeners are a different story. They have been upgraded by technology to make life easier for both students and teachers. Here’s proof:

  • They save time – Electric pencil sharpeners are very fast. Some will sharpen five pencils in the time it would take to sharpen one manually. In an office, time may be money, but in a classroom time has a different value. Children will waste time sharpening pencils, making a mess and take even more time cleaning it up. All of this reduces the amount of time they have with you.
  • They save money – How can a pencil sharpener save money? First of all, you only need one. You may have to buy small plastic or aluminum sharpeners throughout the year as they go missing. Also, since electric sharpeners work more efficiently, they save pencils. The point won’t break when you pull it out leaving a blunt edge that needs to be sharpened again.
  • They are efficient – You can set the sharpener and it will sharpen each pencil the right amount and stop. This stops students from reducing the pencil to the nub trying to get the perfect point.
  • They are easy to maintain – Most electric sharpeners have replaceable parts, so you can replace the blade when it gets old and dull. With a conventional sharpener, you have to discard it and buy a new one.
  • They collect the shavings – With a collection chamber that holds up to 50 pencils’ dust, you only have to empty it once in a while and you never have shavings on desks, the floor or mixed with supplies.

Here are the results of my research into the best electric pencil sharpeners for teachers that are available today. My focus, of course, is in the classroom, but each of these is suitable for home or office.

1. Bostitch QuietSharp Glow Electric Pencil Sharpener

This sharpener works automatically when you push the pencil in and works manually if you put the pencil in and rotate it. It takes three to five seconds to sharpen a pencil. When sharpening, you may need to hold on to the sharpener because it is very light and not very stable.

This model is not so easy to clean as the above models.

What About Mechanical Pencil Sharpeners?

There is a big demand for electric pencil sharpeners because they are fast, efficient and clean. But the electric engines make noise, some less than others, and this can be a big disturbance in a classroom.

The two main types of mechanical pencil sharpeners are bladed and rotary.

Bladed – This type uses wedge technology to cut the pencil. It works like a sword or razor. The wedge transfers the horizontal push of the handle into a vertical force to shave the pencil. In a small hand-held sharpener, it haves the pencil as you turn it.

Rotary – this is the type you may have used during your elementary school days. You stick the pencil on one side and turn the crank on the other side. Two cylindrical cutting blades are at 23-degree angles to each other. They cut your pencil into a conical shape. This type is also called helical sharpeners.

Some of the main benefits of mechanical sharpeners are:

  • They cost less
  • They are virtually silent
  • They can sharpen with remarkable precision
  • They are easy to use

Here are the results of my research into the best manual pencil sharpeners for classroom use:

6. Bostitch Metal Antimicrobial Manual Pencil Sharpener

Bostitch Metal Antimicrobial Manual Pencil Sharpener

This is an all-metal sharpener that should stand up to heavy usage in a classroom. The cutter is easy to remove without the need for a tool for cleaning. It is also antimicrobial protected.

Best for: This is a good manual sharpener for those of you who can’t stand the sound of an electric sharpener. It also has Tip Saver technology to stop the cutting when the pencil is sharp, so children can’t grind the pencil to nothing in one go.

The sharpener is pretty self-explanatory, but this video gives a lively explanation of how to attach the sharpener, clean it and use it. It just takes a few minutes, and I recommend you watch it.


7. AFMAT Pencil Sharpener

AFMAT Pencil SharpenerThis is a long-point mechanical sharpener. You may not be aware of what it is. I wasn’t. It gives a needle-sharp, extra-long point for artists. It comes with instructions because it doesn’t work as a conventional sharpener. It works with graphite, charcoal, watercolor pencils, colored pencils with soft leads. This means no wax pencils.

This video is worth watching to give you an idea of this unusual type of pencil sharpener before you buy it.

How to Choose the Best Pencil Sharpener for Your Classroom

School children use pencil sharpeners several times every day. As already mentioned, the pencil sharpener can be a gathering spot for children to whisper, giggle and generally waste time. But, they need good tools to do their work, and a sharp pencil is one of the main tools they need. Here are a few tips to consider when you want to purchase a new pencil sharpener for your classroom.

  • Power – Decide if you want manual or electric. Most teachers prefer electric because it gives them more control over the device. The one I like lights up when the pencil is sharp and stops working. This is good because the student can’t stand there forever grinding down their pencil.
  • Size – The sizes range from the smallest pocket models to large, heavy devices. The larger models will accommodate several size pencils, usually from six to eight different sizes. They are also heavy-duty and can handle a large volume of pencil sharpening. This is why the larger models are more suitable for a classroom. Small pocket-sized sharpeners are good, but as I said earlier, they tend to get lost or disappear, and you need to keep buying them. But, you can always tell your students, if they lose them, they are responsible for replacing them. However, this doesn’t always work.
  • Safety – If your students are going to operate the pencil sharpener, it needs to be safe to operate. That’s why I like one that turns off when the pencil is sharp. It also won’t run when the shaving reservoir is removed. For the youngest students, they shouldn’t be able to put their fingers in the hole.
  • Type of pencils – If you plan to only sharpen the usual No. 2 graphite pencil, you can choose any sharpener. If you are an art teacher, you should select one that will sharpen all types of colored pencils such as the AFMAT Pencil Sharpener. If you plan to sharpen conventional classroom colored pencils, you should get one that has removable blades or that is easy to clean.

FAQ

✔ What is an antimicrobial pencil sharpener?
A pencil sharpener is called antimicrobial if it chews away the outer coating of the graphite inside the pencil to release a powerful antibiotic. The antibiotic is embedded in the pencil and can kill E. coli bacteria. I think this a great invention and worth every penny. In most classrooms, pencils and fingers go in mouths, so having a sharpener that kills the bacteria is worthwhile.

✔ What is the best pencil sharpener for colored pencils?
Most ordinary colored pencils used in classrooms are made with wax. This can stick to the blades and cause them to be dull. After sharpening many colored pencils you need to clean the blade. That’s one of the main reasons I like the Bostitch Antimicrobial QuietSharp Glow Extra Heavy Duty Classroom Electric Pencil Sharpener. The blade is easy to wipe clean.

✔ Can a pencil sharpener sharpen standard-sized crayons?
If there are two holes in a manual pencil sharpener, the larger hole can be used to sharpen wax-based crayons. It is meant for softer material, but oil-based crayons will clog the sharpener. You may need to use a bit of isopropanol alcohol and a toothbrush to gently brush the wood shavings that have become stuck to the blade because of oil-based crayon debris.

Final Thoughts

Pencil sharpening was a messy and time-consuming activity in my classroom before I got an electric sharpener. I had no idea there were so many types of sharpeners until I started my research. This blog is intended to save you time when you are looking for the best sharpener for your classroom.
