Best Pencil Sharpeners of 2020
The X-ACTO School Pro is a workhorse pencil sharpener made for high volume usage across a variety of pencil types including color, graphite, or charcoal of varying hardnesses. This unit has 6 preset pencil diameters covering a wide range of sizes up to 10 millimeters. The large, clear shavings container is easy to monitor, and the "fly away" spiral blade disengages when a fine point is achieved to reduce oversharpening. This model comes with a 10-year warranty and replacement parts are available from the manufacturer. These benefits speak to the quality and durability of the product.
While we were quite impressed overall with this sharpener, we had trouble keeping the suction cup feet secured to the surface of our desk. Additionally, this model isn't as quiet as we'd like for classroom or library usage. This issue is worsened when sharpening large diameter pencils because the machine slows under the load. Lastly, this unit is relatively expensive compared to the other machines in the class. That said, few of the sharpeners that we have tested are able to bring such a wide variety of pencils to such a fine point in such short order.
The KUM AS2M uses two separate sharpeners in one unit to first render the wood into an elongated cone and then shave the lead to a point so fine as to be delicate. The palm-sized sharpener easily fits into a tote or briefcase and the clear shavings bin lets you know when it's time to empty the filings. The sharpener can handle 8 mm diameter pencils, but it's designed for the 2- and 3.15-mm lead common to art pencils.
The KUM makes use of two razor blades, one for each stage of the sharpening process. These blades are effective, but the second stage tends to break-off the fine lead point if you're not careful. Moreover, this unit doesn't do well with color or charcoal pencils. Odd-shaped pencils, such as those with a triangle cross-section, are difficult as well. Finally, given the manual nature of this model, it is quite slow to sharpen a new pencil. Despite these shortcomings, the sharpener is a boss for its size and produces one of the finest tips of the group.
The handheld Toolstand Electric Pencil Sharpener is unique in that it is both a battery- and manually-powered device. As such, if the situation calls for it, or you're just out of batteries, you can silently clean-up the tip of your pencil. This model can handle a variety of pencils sizes (up to 8 mm), types (graphite, color, and soft charcoal), and shapes.
Although the Toolstand is versatile, it struggles with certain tasks. Namely, the sharpener doesn't do well with hexagon-shaped pencils or charcoals that are on the harder side of the spectrum. Moreover, we would not recommend this unit to kids because it requires a fair amount of grip strength to hold the pencils against the single razor blade that shaves them down. Despite these limitations, this unit is inexpensive, compact, versatile, and effective.
The scholastic classic X-ACTO Ranger 1031 may induce feelings of nostalgia for elementary school arts and crafts. This hand crank unit requires neither electricity nor deskspace. The wall mount makes turning the handle a breeze and the lack of a motor keeps the sound to a minimum. Moreover, this machine can handle a broad range of pencil diameters ranging from 4 to 12 millimeters and will bring all these sizes to a fine point. This model comes with a 10-year warranty.
There are several features we like about this model, but in some people's eyes the same features may be seen as drawbacks. Such is the case with the wall mount requirement on the Ranger. If you don't have a place on your wall to mount this model or you don't want to put screws into your wall, then it's not for you. Also, if you don't like hand cranking, then it's also a no go because there is no electric option. Finally, this model won't sharpen charcoal. However, if you want a quiet, reliable machine produced by a company that will stand behind their product, look no further.
The OfficeGoods Electric & Battery Operated pencil sharpener is a nicely designed product and it handled all the pencil types that we threw at it — namely graphite, color, and charcoal. The machine sharpens fairly fast (7 seconds for an 8 mm graphite pencil) and, perhaps best of all, you can set the tip angle to blunt, medium, or sharp to match your preferences or intended use.
Conversely, the OfficeGoods sharpener requires you to be observant when bringing pencils to a point because the machine does not effectively stop sharpening when the desired angle is reached. As such, it can eat up a pencil if you're not paying attention. At the same time, the single blade digs into the pencil with enough force to make holding a pencil stationary relatively difficult. That said, we think this machine is a good product all around for those sharpening a diverse pencil selection to a variety of point angles. Moreover, the two power options (plug-in or battery) gives the user flexibility.
The AFMAT Electric Pencil Sharpener has a narrow range of pencil types that it performs well on. When using a standard 8 mm pencil, however, it works great. While the unit only uses a single spiral blade, its construction is entirely metal — a more robust design to be sure. Finally, its shavings bin is amply sized for heavy use and infrequent emptying.
Unfortunately, the AFMAT's feet are not very grippy which makes using it a two-handed operation, one on the pencil and the other to hold the machine in place. Additionally, the machine can eat up a pencil if you don't monitor the sharpening. Nonetheless, this machine will sharpen most charcoal pencils as well as achieve beautiful tips on round, hex, or triangular graphite pencils.
The unique design of the Bostitch Personal gives it an interesting look. It sharpens standard pencils to a fine, though steeper point. Additionally, the feet of the unit are grippy enough to allow for one-handed operation.
While we like the look of the Personal, emptying a full tray is a messy affair due to the tapered sidewalls. Additionally, the unit is limited to standard 8-mm pencils. Although it can't handle colored lead, it can bring charcoal pencils to a point with little effort. So, if you're looking for an electric unit that can be used one-handed and looks interesting to boot, this is the ticket.
The STAEDTLER 511 is a great travel-size sharpener for a backpack or tote bag. The cylindric design is easy to grip and the tip it produces is finely acute. This unit can handle several pencil diameters and lead types. It's also inexpensive and simple to operate.
On the flip side, it took us a long time to sharpen a fresh pencil with this manual unit. Additionally, the filings bin is small, and you can only check it by unscrewing the lid because it's not transparent. That said, this unit will handle a variety of pencil shapes (including triangular), and lead types (including color, and to a lesser degree charcoal).
Why You Should Trust Us
Senior Research Analyst Austin Palmer has been testing consumer goods for the better part of a decade. He often uses a number two pencil to draw out his testing schematics and tools, as well as to take his extensive notes. He knows the value of a sharp pencil and a well-designed sharpening machine. Augmenting Austin's experience is Senior Review Editor Nick Miley. In his previous career as a dendrochronologist, he spent many an hour staring through a microscope at tree cores marking out rings narrow enough to barely accommodate a single dot with a pencil. He appreciates the value of a fine point pencil.
Our team's analysis of pencil sharpeners was straightforward but exhaustive. We sharpened every kind of pencil commonly available and rated the machines on their performance. Namely, these were round, hexagonal, and triangular-shaped pencils with lead types of graphite, color, and charcoal. We rated the machines on the range of diameters they could accommodate as well. Perhaps most importantly, we delved into the convenience features that each machine offered. For example, we timed how long it took to sharpen a standard pencil, how much noise the machine produced, and whether the blade included an auto-stop mechanism to prevent over-sharpening.
Analysis and Test Results
Our analysis of pencil sharpeners relies on four metrics to examine all aspects of a good pencil sharpener. Specifically, these are convenience, lead type, pencil diameter and shape, as well as sharpness and point type. Under each of these broad categories were carefully designed tests to provide a full understanding of each machine and who it will best suit. For the details of each metric and the machines that performed best, please continue reading.
Admittedly, convenience is not a self-explanatory category title. For our purposes it covers aspects of sharpeners such as the number of hands needed to operate the machine, how noisy it is when sharpening a new pencil, how long it takes to bring a new pencil to a head, and the size of the shavings bin. Additionally, we looked at whether the machine has an auto-stop to prevent over-sharpening, what kind of blade it uses, and whether replacement parts are available. Without a doubt, the electric X-ACTO School Pro is the most convenient of all the sharpeners reviewed here. It has a "fly away" blade that never over sharpens, a large filings bin that limits trip to the wastebasket, and it isn't overly noisy or slow in its work. Moreover, the manufacturer offers replacement parts for purchase if the need arises.
Alternatively, if you need a sharpener on the go, a desktop machine won't be convenient at all. If this is your situation then have a look at both the KUM AS2M and the Toolstand Electric Pencil Sharpener. Both units are travel-sized and offer a fair amount of flexibility to sharpen different pencil types. The Toolstand is unique in that it is both manual and battery powered. For added convenience it comes with an extra blade and batteries.
As the name implies, the lead type metric looks at the types of filling in the pencil that the shaper can reliably bring to a head. Specifically, we tested graphite, and color, as well as soft, medium, and hard charcoal pencils for this analysis. Surprisingly, many of the models in our review have blade systems that do not do well with anything but a standard graphite pencil. If you need a sharpener that can do it all, check out the desktop X-ACTO School Pro or the handheld OfficeGoods. Both sharpeners are guaranteed to impress because we saw them perfectly sharpen all lead types including the challenging charcoal pencils.
If you are only concerned with sharpening standard graphite pencils, then have a look at the X-ACTO Ranger. This classic wall-mounted, hand-cranked machine is a workhorse for bringing graphite to a fine point. If color pencils are your main concern, the Toolstand is a pro. As for charcoal, the electric AFMAT does very well but be aware that it's hard to tell when the pencil is sharp, making over-sharpening a real concern.
Pencil Diameter and Shape
There are a lot of different pencil shapes and diameters out there. As such, we looked at the range of sizes and shapes that these machines will accept. Specifically, we looked at round, hexagonal, and triangular shaft pencils. As you might imagine, the triangle-shaped pencils posed problems for several sharpeners. Additionally, many sharpeners are designed for the standard 8-mm pencil type, such as the number two graphite variety made infamous by standardized testing. If versatility is what you desire, look no further than, you guessed it, the X-ACTO School Pro. With the exception of carpenter pencils, there isn't much this machine can't sharpen.
Other products of note are the X-ACTO Ranger which covers diameters up to 11 mm, and pretty much any shape. Additionally, the STAEDTLER is limited to 8 mm diameters, but it can tackle any shape pencil.
Sharpness and Point Type
Regardless of point type, a sharp pencil is desired by all. The angle of that point, however, is a matter of preference and intended usage. For example, if you're doing fine line work, a long narrow point such as that produced by the KUM AS2M or the X-ACTO Ranger might be desirable. However, if you are working on a rough medium such as wood, you'll likely want a blunt tip. Fortunately for those who want options, the OfficeGoods sharpener has three settings (blunt, medium, and sharp) so you can make task-specific decisions.
In this review we tried to analyze and describe every aspect of a good pencil sharpener. Although the desired head on a pencil is certainly an individual preference, we did our best to provide all the details so that you can choose the right sharpener for your needs. Specifically, these features are types, shapes, and leads that the sharpener can handle, the time it takes to sharpen them, the quality of the tip, and the noise they produce to name just a few. So, whether you're a finish carpenter looking for a wide-angle tip or a sketch artist looking for a long, fine point, there is a sharpener here for you.
