Criteria for purchase: What to consider before buying an electric pointer

Compared to their manual and mechanical predecessors, electric pointers have numerous benefits. They are much faster and more convenient to use and because of their collectors, you do not have to worry about dirt.

However, before making the purchase it is important to check some criteria that differentiate the models, so you can be sure that you are choosing the ideal sharpener for your needs.

Analyze each of the topics below carefully and at the end of reading, you will know everything you need to sharpen your pencils without headaches with brittle tips or sore fingers.


The material of the body of the electric sharpener is an important factor that you should consider when choosing the best model, as this directly affects its quality, efficiency and especially the useful life.

If you are looking for simpler models, today many sharpeners are made in plastic, much lighter and easier to carry. But if you want more professional results and a product that lasts for much longer, opt for the metal models.

There is no standard for the blades of electric pointers, so they may vary according to the model or brand of the product. Their useful life also depends on the type of metal they are made of, but inevitably, with use they wear out.

In this case you have a few options, such as removing the blades and sharpen them, look for new blades and replace them, and, as a last resort, buy a new electric pointer.

Therefore, research a little and choose a sharpener with good quality blades, such as those made of carbon steel, which are more resistant and durable. In addition, check with the manufacturer about the availability of blades for replacement.

Pencil thickness

Before making the purchase, check the product specifications and check what thickness of pencils it can handle. Currently, most models are for pencils that have 6 to 8 millimeters.

Especially for artistic work, where thicker pencils are used, look for models that also hold pencils of 9 to 12 millimeters. Many models already offer support for these two types of pencils.

Charging type

When you are choosing the ideal model, take the charging type into consideration. Because they are electric devices, they use batteries or can even be plugged in.

Most models need two to four AA batteries, which are not included and need to be replaced over time. Most manufacturers do not advise the use of rechargeable batteries.

It is also common to find models that use batteries similar to those used in watches, so check the product specifications because the size and model of batteries can vary widely. Finally, in models that use sockets, remember to always check the necessary voltage.

Size of the collector

The size of the collector influences the general size of the product, but it is one of the great highlights when compared to other models. Nowadays it is almost impossible to find models that do not have these collectors.

You should consider the ease of transport, because in these cases a sharpener with a smaller collector is better. For table models, they are usually much larger. Anyway, the bigger the collector, the more time you will have between cleaning and cleaning.
