Mechanical Pencil for Math Buying Guide

Mechanical Pencil for Math Reviews

Although we mentioned the 6 best mechanical pencil for math, without a buying guideline, our article will remain incomplete, so are your questions.

These buying guides will make your choice easier, and here we will make you notice some vital and core information. Then you’ll calculate your budget, demand, and finally can choose the right product for you.

So read through the buying guide carefully. This will help you choose a perfect mechanical pencil from anywhere, not only from our list.

Budget and choice

Before buying anything, first, we make a budget. In the time of mechanical pencil, this is not different obviously.

There are several mechanical pencils, and our choice is also several. Some prefer only one pencil in an amount; some prefer more than one. So first, you need to make a budget and fix a choice, then calculate your demand.

We recommend buying a single mechanical pencil. But if you want to use both as a gift and for personal use, then you can buy a package of mechanical pencils.

Construction type

A mechanical pencil’s quality massively depends on its construction type. Whatever its material is, whether it is metal, plastic, or stainless steel, if it is sturdy and has perfect weight, then it is really a qualitative one.

Most often, metal-based pencils are considered more qualitative, yes, this is true, but plastic pencils can also be intense.

In our list, we have metal, plastic, and stainless steel-based pencils. And these all maintain quality in terms of their price.


We write with pen or pencil but hold this by the grip. The grip is the most significant part of a mechanical pencil because it ensures how comfortable our writing will be.

The maximum time we see the grip with metal, rubber, or steel. Whatever the pencil material is, if its grip is chiseled, you have really got a comfortable grip. When we are in a writing session for a long time, our hands will obviously sweat.

If the grip is chiseled or has soft latex-free pads, then the possibility of hand slip reduces. For people who have small hands, a narrow grip is for them. And who has large hands, also joint problems should choose a thick grip.

Twist mechanism

The twist mechanism is the most useful mechanism for lead advancement. It takes minimal time and effort to make you ready to write and protect the lead, and you just need to push the top button.

The updated twist mechanism gives customers a satisfying experience. On our list, each pencil has a twist mechanism that is retractable easily.

Lead size and grade

While buying mechanical pencils, people most often focus on construction, grip. But along with this, it is similarly essential to know about lead size and grade. 0.5 mm lead is comparatively thinner than 0.7 mm and creates a thin line also. To do the math, you can choose the one you prefer.

But for drawing or sketching, you should prefer 0.7 mm lead. And about the lead grade, for math, it is better to go with HB leads.

These create thin lines or sharp lines. HB is also used for drawing and sketching too. But comparatively, 2B leads are better for drawing purposes.


Purchasing a mechanical pencil without a built-in sharpener will not help you much. Doing mistakes in math is normal. After an error, if you find the eraser ready for you in pencil, it saves your time, and you don’t need to carry eraser separately.

Frequently Asked Questions

1. Which mechanical pencil is best?

The mechanical pencil that has an ergonomic design, sturdy construction, comfortable grip, good lead refills, a built-in eraser is called the best mechanical pencil.

If you directly want a name, then I would recommend pentel graphgear 1000 and Rotring 600. Both are leading the market for a mechanical pencil.

2. 0.5 or 0.7 Which One is Better?

0.5 mm lead, and 0.7 mm lead are most used, and both are better in a specific perspective. 0.5 mm is to create thin and sharp lines as the lead itself is thin, which is considered better for regular writing purposes.

On the other hand, 0.7 mm lead is thick and creates bold lines. This is considered to be better for drawing purposes. But this can be used for writing objectives too.

3. Which is lighter HB or 2B?

HB and 2B are two different lead types. In HB, graphite is used less, and clay is more. Thus HB lead is lighter and primarily used for writing purposes, but drawing is also possible.

In 2B, the amount of graphite is more. For this reason, 2B is darker than HB. And 2B is mostly used for drawing sessions.
