Lead holders are quite common if you venture into an art supply store. I prefer them to normal pencils because you have the full length pencil even when the lead is tiny.
These ones look very nice though.
These ones look very nice though.
They also were once common for manual drafting.
I have several and in my engineering and drafting education were referred to as drafting pencils. They have that cool whirly sharpener too.
One of fmy favorite holdovers from the old world is that you can still buy them, along with a few other basic hand drafting tools from office supply stores like office depot. Stadler is one of the big brands.

Mom and dad were architect and engineer in the transitioning period to CAD software and still remember my days spent sharpening drafting pencils by hand on Stadler sand paper holders. Koh-i-noor is another brand I remember.
"Staedtler", and their products are typically excellent - I have a compass from them that's about thirty years old and still going strong, along with sundry pencils, erasers, and a leadholder or two of more recent vintage. Not that I've ever been very much of a draftsman, but at least when I screw up I know it's not my tools to blame...
There's this great YT channel of a guy who inherited his grandfather's metal shop, including a drafting table. He likes precision and proper drawings.

That channel is great, but as with many I suspect that there is some sort of "shadow industry" that creates great YouTube channels "from scratch".
If you compare inheritance machining to e.g. this old tony, the later has years of growth with the videos getting better of the years as he refines his formula. In comparison inheritance machining just popped up with perfect content, script and video editing.
There are other examples of channels that just popped up that start at a very high quality level that I suspect some third party involved in that process.

I'm not quite as cynical about Inheritance Machining. Yes the quality is superb, both in video production values and subjects, but I think we're at a point where it's not that hard to create quality visual content if one cares to. High quality cameras are relatively cheap, editing software is excellent, and in many ways, a new YouTuber is standing on the shoulders of giants who created the path. Look at Marques Brownlee, arguably one of the best YTubers. He had to define what a review YTuber looks like. The next big YTuber will simply follow the same paradigm.
Compare this to someone ten years ago who was trying to do this with Super-VHS etc, with software that was very expensive, and forget about doing anything multi-camera. So the tools are just far more accessible.
Then combine that with a creator who has seen what works and doesn't work on YT/Insta. You need a good thumbnail, you need less talking heads etc etc.
And I think that Brandon at Inheritance Machining is very detail oriented, as you would expect from someone doing machining. This probably translates well into producing a quality video.

Or NileRed. The guy isolated fucking bromine in a barely ventilated and cramped with clutter garage when he started, and now he's running his own legit laboratory together with (IIRC) his brother and a friend who's running the camera.

Now I know they are called drafting tables! Still got two in the old office of my parents.
Fun tidbit, the Japenese word for a mechanical pencil is two english loan words, Sharp Pencil ( シャープペンシル )
And apparently the creator of the "Ever-Ready Sharp Pencil" in Japan went on to found the electonics company "Sharp", whose name is derived from the pencil:
> The mechanical pencil became successful in Japan with some improvements in 1915 by Tokuji Hayakawa, a metalworker who had just finished his apprenticeship. It was introduced as the "Ever-Ready Sharp Pencil". Success was not immediate since the metal shaft—essential for the pencil's long life—was unfamiliar to users. The Ever-Ready Sharp began selling in huge numbers after a company from Tokyo and Osaka made large orders. Later, Tokuji Hayakawa's company got its name from that pencil: Sharp.

Kitaboshi Pencil Factory is within cycling distance from my home in Katsushika ward. This news item makes me so happy! You don't see things from your neighborhood make to the trending HN section everyday :)
It's been ~40 years, but this brings back a delightful memory of being bored in middle school, and drawing out a design for a pencil factory.
I don't remember all the details, but their design is probably a little better.

Our story starts with Hakomiru, a man who has studied diligently all his life in the art of pencil-making. He first apprenticed with his grandfather 58 years ago, and inherited the the family tradition several decades later. Hakomiru will walk 11,000 kilometers in the coming year, exploring forests and woods looking for the perfect lumber for his pencils. Not just any wood will do. Once a tree is selected and a price negotiated with the owner, the process of felling this tree will begin. Delicate wood saws are employed, no axes as these impact on the tree stump may subtly alter the grain. These saws cost upwards of $40,000 and must not be mistreated! Our artisan Hakomiru will spend no fewer than 16 days sawing it at exactly 67cm above the point at which the tree meets the soil. As the saw approaches the point at which the timber may start to fall on its own, Hakomiru hurries to retrieve it so that it isn't twisted in the felling. The saw will not be ready to fell another tree until it has been polished by a master sawblade polisher, a job that can take up to 18 months! Next, Hakomiru loads the log onto a traditional pencilmaster's log-hauling cart, which he and his assistants will pull by hand into town. From there, it will be loaded onto one of Japan's 296 maglev high-speed trains, where it will take another 17 minutes before it arrives in his workshop on the other side of Japan. Hakomiru is very excited, this may be the best log he has ever harvested and well worth the $190,000 price tag. But that is still unknown, and will be until he can peel the bark in a grueling 30 month ordeal. Should things turn out well, the log can then begin air drying. A translator speaks: "We never let the lumber air dry less than 22 years, and with luck I will live to see this one ready for the next phase, since I will only be 94 years of age at that point!"
I always wonder, when I see videos like this: who creates the system of little machines that nudge, shove and knock items from one step to the next?
What's their job called? And when that is your job, can you just go into any factory and come up with the answer – or do you specialise in a certain field? And all the parts you use commodity, or are they specific to pencil making, for example?
If anyone has any light to shed on this field of work I'd be interested to learn more.

Industry automation companies. A big part of the German Mittelstand - a ton of companies of all sizes, from small ventures like HEITEC over mid-sized like KUKA (the robotics guys that the German government in all its ignorance tolerated to be bought up by China) to giant megacorps like Siemens.
Particularly the small shops aren't really known, not even here in Germany... but worldwide, out of ~3.400 businesses classified as "hidden champions" aka market leaders in their niche worldwide, Germany has 1.573 such companies, surpassing everyone including the US worldwide by far [1].
Think of it like YKK from Japan, the undisputed champion in high quality zippers, just even less known to the general public... such machines that nudge, shove and knock items, each of them is made by a dedicated German company specializing in a specific type of machine, made with parts made by another dedicated German company. Yes, conglomerates could gobble all of that up and use advantages of vertical scaling, but they're all owned by the founder families and their descendants, in many cases across many generations. They won't ever sell out or share their knowledge, and so they remain in business because they have ironed out all kinks and wrinkles in their specialty machines over decades if not centuries - and upstart competitors have to start from scratch. On top of that, their staff is extremely loyal, you can't just go and poach them and their knowledge.

Those are production engineers.
Curiously if you dig into the whole Toyota Production System/Kanban/JIT literature you encounter a lot of this, especially the work of Shigeo Shingo who came up with the mistake proofing/zero defects/single minute exchange of die ideas. Most of the actual tactics in use are shockingly simple, but it is the ability to move the needle to total reliability that makes the difference.

I reckon that is called material flow and logistics and is an area inside mechanical engineering schools. I worked in the past for companies doing just that in every size from a pencil to parts as big as a car.
In a similar vein, but for different products, but also with much more focus on the "back end" of the process:

I visited the Caran d'Ache [1] factory in Geneva a few years back, it's very similar [2]. Except they have a system to be sure all the pencils are in the same position in the box, with the name on top. It's a system with a camera and shape recognition, used for high end sets.

It is not immediately obvious, but the video has subtitles explaining the whole process.
I wouldn't say it's exactly the "whole" process.
To make a pencil, you must first create the universe.

True for so many 'simple' items in our world of mass-production. 100's if not 1000's of people laboured to bring even the simplest items into existence.

Shallow depth of field looks really cool when the subject is actually in focus, but just looks like crap when nothing is in focus. Lots of close ups of random parts of machinery that is not obvious what so ever is the intent of what's supposed to be shown. It was almost a cool video.
Surprisingly manual intervention seems to be required
My guess is it is probably cheaper than fully automating the process with machines.
It is, or rather they may not have enough production volume to justify full automation. Buying the machinery and setting it up to automate a production line only makes sense when your volumes are massive.
I didn’t watch the video but $DAYJOB is a consumer goods company that manufactures, some fully automated some with human operators.

wood quality is quite variable so it's to be expected.
I've done some factory automation. Something I learned is that automating the last 20% of the process takes 80% of the work. Removing the last remaining manual processes gets exponentially harder and more costly.
And often in doing this last 20% we come across the fact that the human portion of the assy process does so much more than it seems on the surface. Things like predicting and correcting for errors, keeping things going that aren't immediately obvious.

Wow, I love small machine shops!
I love these industrial machinery videos. I wish I had done the necessary subjects at university to go into this.
the clicking and clacking and movement is very soothing. This machinery is probably 50 years old tho. I went to a glass factory that was using equipment from over 100 years ago.
My thoughts exactly. What am I seeing that wasn't obviously not available in the 1950s?
Anyone know what the labels on the defect bins were? Or what was written during the pencil test at the end?
The labels on the defect bin were things like scratched, rough, curved, stuck together, and uneven coating.
北 = kita (north) 星 = boshi (from hoshi, meaning star) 鉛筆 = enpitsu (pencil)
So … "Kitaboshi Pencil" or "North Star Pencil", the company name.

I love this channel it's very relaxing just to watch them go about their business.
Fun video. I don't think I've used a wooden pencil since 6th grade tho.
