Cross mechanical pencil disassembly


We love mechanical pencils. You"d probably guess that from the expensive number of them we stock. There"s an amazing variety of mechanical pencils easily accessible, in all sorts of styles, via all sorts of functions, for many type of various functions. So we believed some sort of overview can be beneficial. We"re aiming for this overview to serve several purposes:

If you require some tips on using your pencil (pun intended), we can aid. It"s not constantly obvious just how to include spare leads, for instance, or clear a jam as soon as points obtain stuck.If you desire to buy a mechanical pencil, but you"re not certain what form would certainly be ideal, we have actually a couple of ideas. The finest pencil for you could depfinish on most points, yet we"ll aid you narrowhead points down.We additionally hope it will be an interesting review, if you find mechanical pencils interesting. We do!


What Is a Mechanical Pencil?

Definitions vary, but for the function of this short article, we"ll think about a mechanical pencil to be any pencil through a lead-development mechanism that pushes the lead forward in some method. We"ll point out clutch pencils briefly as well, wbelow the lead is released as soon as you hold dvery own a button, but we think about those to be a sepaprice form. Woodcased pencils are obviously not counted here, but that doesn"t suppose we do not love them too.

Other Names for Mechanical Pencils

Mechanical pencils might be referred to as various things in different places, by various civilization. Here in the UK, "automatic pencil" and also "propelling pencil" are rather common terms, and civilization might also refer to "clicky pencils". Ones designed for technical illustration might be described as "drafting pencils" (or also "draughting" in British English), or "technical pencils", though these terms have actually additionally been supplied for traditional clutch pencils.

Although not used below, Wikipedia tells us "pen pencil" and also "lead pencil" are used in India, and "pacer" is supplied as a generic term by some people, though it"s actually the name of an old Paper Mate pencil. We"ll stick to "mechanical pencil" right here.

History of Mechanical Pencils

The initially pencils were even more prefer modern-day clutch pencils than what we now think of as "normal" wooden pencils. Graphite was initially offered in lumps, with possibly a bit of fabric wrapped about to hold it. When points began to progression towards the pencil, the first attempts affiliated wood holders to grip sticks of graphite, so they might be supplied even more conveniently and also cleanly. The initially summary of a leadholder was by Conrad Gessner, ago in 1565.

If you desire to be really conventional, Cleo Scribent make a replica, dubbed Der Gessner. It"s quite fiddly to readjust, bereason there"s no spring device, yet the fundamental elements of a clutch pencil are all there.

For many type of years, push-fit lead about 1.18mm in width was the majority of widespread, via a twist mechanism that wound the lead down choose a screw as it was used, and pencils were frequently decorated via ornate designs in sterling silver.

The should compose elaborate characters expected Japan had a better impetus to make thinner leads, which cause the birth of the modern mechanical pencil there.

Tokuji Hayakawa made the "Ever-Ready Sharp Pencil", which was a substantial success, and his company took the name of the pencil, and also ended up being "Sharp" - the electronics agency we know this particular day.

Thinner lead wasn"t feasible through the traditional mix of graphite and also clay, as it was too brittle. Modern thin leads are based upon high-polymer organic products that can take a lot more force without breaking, and they"re obtaining much better all the time.

Why Use a Mechanical Pencil?

There are some excellent factors why you could prefer a mechanical pencil over a woodcased pencil.

No Sharpening. If the lead is thin enough, you don"t have to save sharpening it - just save writing or illustration. Not only does it save time and initiative, however sharpening can be messy.Consistent Line Width. When a woodcased pencil is freshly sharpened, it writes an extremely thin line. As shortly as you"ve written a bit, the line gets thicker and also thicker. With a mechanical pencil, the line states the same, so it"s a much more predictable tool.Consistent Balance. As a wood pencil gets shorter, the balance changes. Mechanical pencils don"t change as you use the lead. It"s not hugely necessary to everyone, yet some artists discover this makes a big difference for them.Refillable. You do not throw ameans stubs, you simply save putting more leads in. There are no trees to be cut dvery own. It can be said that mechanical pencils are the even more environmentally friendly option, if you use one for a lengthy time. Given that the leads typically come packaged in plastic boxes, though, it"s not a simple calculation to know which is better, yet there"s a lot to be said for a solitary tool you can usage for years.Choice of Styles and also Materials. Mechanical pencils can vary hugely in how they look - some look choose technical tools, some look favor high-end products, and also some look prefer easy plastic-bodied pencils. Some also look prefer wood pencils!

Not that we have actually anything against other types of pencils - we have several clutch pencils, and also a large array of woodcased pencils right here at Cult Pens, and also they"re all ideal tools for someone. A wooden pencil can make a broader array of marks, and also has actually a particular simplicity that mechanical pencils can"t match. It"s perfectly possible to love them all!

Using a Mechanical Pencil

For the the majority of part, mechanical pencils are quite simple to use - with a lot of of them, you just click the switch on the finish to feed out even more lead whenever you must. Retract the lead by holding the button in and also gently pushing the lead in. When one stick of lead is provided up, keep clicking until the following appears. When you"re all out, simply add even more leads of the best size, commonly through a hole under the switch, regularly hidden under the eraser.

Tbelow are some variations and oddities, though…

Twist-click Mechanisms

This mechanism is the majority of prevalent in pencils that are designed to go through a corresponding ballsuggest pen. You twist the height part of the barrel, and also the lead clicks forward. Release, and also the height component springs ago, however the lead remains put. Twist and also hold, and also you can push the lead ago in. It"s just like the clicky mechanisms, however twisting takes the area of pushing. These commonly pull open in the middle to include even more leads.

Inside, this kind of pencil frequently supplies an adapter, equivalent in form to the refill for the equivalent ballpoint, which contains the entirety pencil system and lead tube. Essentially, the pencil is a ballallude pen through an adapter fitted to rotate it right into a pencil. There"s typically a cap at the optimal of the adapter which you remove to include even more leads.

(Several of the pencils at that attach will certainly be of the other twist type, yet we"ll cite those particularly in the following area.)

Continuous Twist Mechanisms

These aren"t so prevalent these days, however there are a couple of roughly, favor Faber-Castell"s e-motion. The inside is a sort of screw-mechanism, wbelow you wind the lead dvery own as it"s used. When you finish a lead, you rerelocate the little stub, and press a brand-new lead right into the system, and wind it back as much as the optimal. Sometimes these only organize one lead, but they regularly have actually somewhere to keep spares. The e-activity, for instance, has actually area for 6 added leads covert behind the nose-cone.

Shaker Mechanisms

Anvarious other solution to the difficulty of avoiding to click out even more lead is the shake device - give the pencil a firm shake up and dvery own, and also a weight surprise inside does the job of hitting the button for you. These normally have a switch in the usual location too, however a quick flick of the wrist takes much less time ameans from scribbling dvery own your notes.

Auto-feed Pencils

Some pencils don"t make you stop at all to extfinish even more lead, at least until you reach the end of a stick of lead and also have to click the following one through. The method these job-related deserve to be a little unmeant, as you have to compose via practically no lead visible at all.

There is a (usually) plastic cone roughly the lead. Generally, you"d have to make certain you clicked out even more lead before it wore dvery own enough to reach the sustaining tube or cone, yet not via an auto-feed pencil. Just save writing or drawing. When the lead wears dvery own enough that the cone touches the paper, the cone is puburned earlier up a tiny method. A spring inside pushes it earlier, feeding some lead earlier down via it. The outcome is that the lead will wear down till it reaches this cone, however then won"t go additionally.

It sounds as though it would be uncomfortable and scratchy to write through, yet the cone is smooth and also rounded so it doesn"t catch the paper. You may still find it even more comfortable to click lead out the usual way once you have actually time, yet if impetus strikes, just save scribbling!

Sliding Lead Sleeves

It"s a little subtle, yet we"re going to make a distinction below between pencils wright here the sleeve that surrounds the lead can slide up if pushed; and also pencils where the sleeve is designed to slide up easily while writing. A few pencils now have actually sleeves via edges that are smoothly rounded, so they will not catch on the paper, and also made to slide up really quickly. The result is that you can keep composing in the very same method you can with an auto feed pencil. The difference is that these pencils won"t actually feed out any more lead, so you"ll have to soptimal and click inevitably. By that allude, though, there"s bound to have actually been sufficient of a pause in proceedings for you to give the button a click.

Kuru Toga

Probably the greatest invention in mechanical pencil technology in the last few years, the Kuru Toga is, quite literally, revolutionary! As you compose or draw via it, the up and also down activity is offered to turn the lead.

Because a pencil is normally organized at an angle to the page, the lead wears dvery own at an angle, and develops a chisel-shaped reminder through a sharp point. This form provides for a thicker line, and also the sharp point deserve to capture on the paper. Some civilization naturally job-related roughly this by turning the pencil as they go, wearing the lead dvery own more evenly. The Kuru Toga does this for you. The result is a finer line, and also much less lead breakage.

While it most likely functions ideal through Japanese characters (yes, no surpincrease, it was designed in Japan!) wbelow the pencil is lifted from the paper several times for each character, it still works well via English writing, and also also helps a little through cursive manuscript.

Twist-extfinish Erasers

With a lot of mechanical pencils, the eraser is there for emergency usage just. If you needed to erase a lot, you"d probably want a separate eraser. A few pencils, though, have actually bigger erasers, through twisting mechanisms to extend them, so they have the right to last a long time. If you erase frequently, it"s a great feature.

Lead Jams

If you usage mechanical pencils, at some suggest you"re likely to have actually a lead jam. It happens. A tiny bit of lead gets stuck somewright here in the mechanism, and also stops it from working. Lead might not click forward, or it could click forward however slide ago in once you try to usage the pencil.

Many mechanical pencils can be dismantcaused some extent to clear a jam. Typically, the component close to the tip unscrews, which allows you view the device. If you then press the switch down versus your desk, the clutch system pushes up. There"s a brass ring roughly the clutch jaws, holding them shut - push it dvery own, and it will release the jaws. Once they"ve sprung open up a bit of sidemethods tapping should dislodge any tiny bits of lead.

If the device can not be opened up up, blockperiods have the right to typically be cleared by holding the pencil tip-up, with the switch held dvery own versus your desk, and also feeding a cleaning pin in with the guideline to press any kind of bit bits of lead out from wbelow they"re stuck. Some pencils encompass a cleaning pin, attached to the eraser, yet many don"t. If you do not have actually one to hand also, an additional piece of thin wire or a pin might fit, but don"t force anypoint too wide into the pointer. At a press, a spare piece of lead can do the project, but it takes a stable hand also to feed it in without snapping it!

Multifeature Pens via Pencils

A lot of multipens have pencils as one of their attributes. These are the majority of commonly either twist-action or gravity choose models, and the pencil system and lead chamber are all fitted into the room of among the tiny ballsuggest refills. They commonly operate prefer a lot of pencils carry out, by just clicking a button on the optimal to extend even more lead. Adding even more lead is a bit even more fiddly, and also mostly involves pulling the little pencil mechanism off its mounting, simply prefer you would to change the ballpoint refills. There"s room for a few leads in the tube it fits onto, however do not put as well many kind of in tright here - 2 or three spares is all there"s area for.

These aren"t the best pencils for heavy individuals, however if you just need a pencil periodically, they deserve to be right - a pair of different ballallude colours in one pen is rather valuable, and a pencil thrvery own in so it"s constantly handy!

Buying Guide

Buying a mechanical pencil is easy. It deserve to be a bit even more difficult to buy just the right mechanical pencil for you. And maybe even more tough to buy the ideal one for someone else. The great news, though, is that they"re virtually all rather dependable and also tough, and also a lot of are rather comfortable to use, so it"s unlikely you"ll go also far wrong.

If you"re the kind of perkid who likes to put a little bit of believed right into this kind of decision, though (and also most our customers are), we"re here to help.


It"s not a poor principle to begin via thinking about what you"re most likely to usage the pencil for. If it"s mostly going to be for composing, you"re probably going to look for different features to someone who will certainly use their pencil for sketching.


If you"re going to be creating via your pencil, you"ll desire lead thick sufficient that it won"t break also quickly. With modern-day leads, 0.5mm is fairly solid enough for a lot of people, but even more heavy-handed civilization do sometimes uncover they snap such thin leads, and also 0.7mm or even 0.9mm leads are much better for them. Some have actually cushioned lead, wbelow an internal spring cushions the lead against stormy treatment.

If your creating includes the sort of notes where you sometimes simply can not sheight scribbling, prefer taking down lecture notes or meeting minutes, you might desire to consider pencils that make it simpler to feed more lead in a rush, via shaker mechanisms or side butloads. Auto-feed pencils deserve to work well, also, maintaining the lead usable at as you keep going.


Drawing or sketching can have actually rather various demands to writing, and have the right to require a little of exploring to see what suits you, and what feels right for your style.

Lead thickness is very essential for drawing. Rough sketching deserve to benefit from thick leads, for bold lines, typically using softer qualities of lead. For this style, you might well want to take into consideration clutch pencils too, as tright here are even more of them available with thicker lead. 0.5mm is the classic size for more technological layouts, but the humble 0.5mm mechanical pencil is an extremely functional tool, and is offered by many artists for all sorts of layouts. For comprehensive illustration, you can desire to consider 0.3mm leads.

If the pencil is going to live in a pencil pot on your desk, it won"t issue much to you if it isn"t pocket safe. If you"re going to be sketching out and about, though, it can be extremely crucial. Conical tips aren"t typically too riskies anymethod, yet tubular tips have the right to be a little also sharp to desire them in your pocket if they do not retract. For quick and straightforward retracting, a "double-knock" mechanism helps - the mechanism is retracted via either a side switch or a firmer press of the finish button. Others may require you to press the pointer in versus somepoint while holding the button down.

If the eraser is necessary to you, you"ll need to make certain it"s an excellent size, most likely of the extendable form. These typically twist up and also dvery own to expose even more eraser as required, normally with the added bonus that you can twist it earlier dvery own out of the method as soon as pocketing the pencil. For drawing, though, you may currently have actually a desired eraser that you"ll bring individually, in which instance, any eraser would certainly be for emergency usage just.


Mechanical pencils have the right to have a surpincreasing array of features. If you think the number of possible attributes to consider is a little bit much when you"re trying to choose which pencil to buy, simply imagine how it is for someone who has to create an write-up all about them!

Here are some of the features you might want to think about as soon as buying a mechanical pencil.


The timeless device for feeding lead is a switch on the oppowebsite end to the tip that pushes lead forward one "click" at a time. There"s fairly a complex set of parts inside to make it all job-related, yet it"s all so tried and also tested that they occupational exceptionally reliably, and you deserve to normally acquire years of usage out of also the a lot of fundamental mechanical pencil.

So why might you consider various other mechanisms? Well, side-placed buttons, shaker mechanisms and auto-feed mechanisms can all feed lead a little bit faster. For the majority of people"s usage, it"s not that important, but if you have to keep up through lecture notes or take minutes in meetings, the moment taken to click out even more lead can be enough to put you behind.

They"re all based on a mechanism extremely similar to the push-button clutch, so they"re all generally incredibly trustworthy.


Many mechanical pencils have an eraser. They"re very important to some civilization, and entirely irrelevant to others. If you rarely erase, you more than likely do not care a lot around the eraser. Oddly, though, human being who erase a lot might not care a lot either, bereason they have actually their favourite eraser, and also they"re happy to lug it individually. Those in the mid-ground, who do treatment about the eraser, must consider the size and also replacecapacity of the integrated eraser. They can almost always be reinserted, however make sure you deserve to actually get the replacements. Tbelow are very few situations wbelow spare erasers exist and we do not stock them, and also we do have spares for most of the pencils we stock, however it"s ideal to check if it"s essential to you.

In a lot of pencils, the erasers won"t last lengthy, bereason they"re so small. If you intend to use the eraser sufficient that this is a problem, look for pencils with large extendable erasers. Several various brands have actually pencils with lengthy erasers that have the right to be extended by twisting.


You more than likely have actually some concept exactly how much you want to spfinish, or at leastern exactly how much you"re willing to spend! There are plenty of perfectly excellent mechanical pencils around for less than £5, yet you might must spend more to acquire what you want.

Tougher develop. While even the cheapest plastic-barrelled pencils have to last well, something via a steel body is likely to be tougher.Features. You may need to pay a small little bit even more if you want a big extfinishing eraser, say, or a quicker method of proceeding the lead.Looks. A cheap plastic pencil will be perfectly useful, yet can not look the part in a meeting. If you"re wearing a nice suit, it would certainly be a shame to have the cheapest pencil poking out of your pocket. Your tastes can be more in the direction of the technological or machined-steel look, however aobtain, you"ll have to invest a little more for the ideal look.Feel. In some ways, this have the right to be the the majority of important thing. If your pencil feels right in your hand also, it have the right to make a huge difference to exactly how much you usage it. The many instrumental component is the grip - you might love knurled metal for the grip, or uncover it too rough; rubber is finest for some civilization, while others like a smooth surchallenge to touch. The remainder of the pencil is probably much less crucial to the feel of it, but it can still make a distinction. More expensive pencils will certainly generally feel more solid than the cheaper ones.

Lead Thickness

If you understand what thickness of lead you want to use, this is a good method to narrow down the selections. Many type of pencils are only obtainable in one dimension, so if you recognize you desire 0.9mm lead, it"s no great looking at pencils only easily accessible in 0.5mm. Many kind of of the even more technological style of pencil are obtainable in a number of different widths, most often 0.5mm, 0.7mm and also 0.9mm, while some include 0.3mm or 2mm to the array.

The thickness you want depends extremely much on your intake, and also counts a lot on personal taste, as well. If your creating is little, or your drawings detailed, you"ll require thinner lead. If you"re heavy-handed, you"ll need thicker lead. 2mm leads are similar in width to the core in a traditional wooden pencil, so for many objectives, you"d have to sharpen them to obtain a sharp sufficient point.

Other Types of Pencils

While this article is all around mechanical pencils, tbelow are various other kinds of pencils to consider - a mechanical pencil isn"t the ideal answer to all problems for all people!

Woodcase Pencils

We"re all perfectly acquainted through wooden pencils - a stick of hardwood with a "lead" core, occasionally through an eraser on the end. They don"t have actually the predictable line width of a mechanical pencil, and also they gain awkward to usage when you"ve worn them dvery own with sharpening. There"s a simplicity about them, though, that"s difficult to beat. That simplicity suggests you constantly understand it"s going to write, and also you have the right to pass one to anyone without having to define anypoint.

Clutch Pencils (Leadholders)

Clutch pencils are carefully concerned mechanical pencils. They use a really similar clutch device to grip the lead, however they absence the added intricacy forced to push the lead forward with a click or twist. Then usually have actually a switch on the end, and also once you press the button, the lead is released. You manually move the cause wright here you require it, then let go of the switch.

They are only normally obtainable for 2mm lead and also thicker, and there are plenty of clutch pencils obtainable in sizes as much as 5.6mm.

To many human being, they combine the best functions of mechanical pencils via the ideal attributes of woodsituation pencils. They do not vary in length as you use them, and also while they have the right to be sharpened to gain an excellent suggest on them, sharpening isn"t essential if you really have to keep scribbling. They keep a lot of the simplicity of a wood pencil, though, via big, basic clutch jaws gripping the lead, and just a spring to make them close and also grip.

The thick lead renders them much less practical for many, though, as you do have to keep sharpening if you require a reasonably thin line.
