- The sound is a really big part,
- I think, of the experience of using a pencil.
- It has this really audible scratchiness.
- The pencil is a very simple object.
- It's made of wood with some layers of paint, an eraser,
- And a core, which is made out of graphite, clay, and water.
- Yet it took hundreds of people over centuries to come to this design.
- And it's that long history of collaboration that,
- To me, makes it a very perfect object.
- The story of the pencil starts with graphite.
- People started finding really useful applications for this new substance.
- They cut it into small sticks
- And wrapped it in string or sheepskin or paper and sold
- It on the streets of London to be used for writing
- Or for drawing or a lot of times by farmers and shepherds
- Who would use it to mark their animals.
- Over in France, Nicolas Jacques Conte figured out a method of grinding the graphite,
- Mixing it with powdered clay and water to make a paste.
- From there, this paste was filled into a mold
- And fired in a kiln, and the result was a really,
- Really strong graphite core that wasn't breakable, that was smooth, usable.
- It was so much better than anything else
- That existed at the time, and to this day,
- That's the method that's still used in making pencils.
- Meanwhile, over in America, in Concord, Massachusetts,
- It was Henry David Thoreau who came up with a grading scale for different
- Hardnesses of pencil, and it was graded one through four,
- Number two being the ideal hardness for general use.
- The softer the pencil, the more graphite it had in it,
- And the darker and smoother the line will be.
- The firmer the pencil, the more clay it had in it,
- And the lighter and finer it will be.
- Originally, when pencils were handmade, they were made round.
- There was no easy way to make them.
- And it was the Americans who really mechanized the craft.
- A lot of people credit Joseph Dixon for being one of the first people
- To start developing actual machines to do things
- Like cut wood slats, cut grooves into the wood, apply glue to them.
- And they figured out that it was easier and less wasteful to do a hexagonal pencil.
- And so that became the standard.
- Since the early days of pencils,
- People have loved that they can be erased.
- Originally it was breadcrumbs that were used to scratch away pencil marks and later rubber and pumice.
- The attached eraser happened in 1858
- When American stationer Hyman Lipman patented the first pencil with an attached eraser,
- Which really changed the pencil game.
- The world's first yellow pencil was the Koh-I-Noor 1500.
- Koh-I-Noor did this crazy thing where they painted this pencil with 14 coats of yellow paint
- And dipped the end in 14 karat gold.
- There's a pencil for everyone, and every pencil has a story.
- The Blackwing 602 is famous for being used by a lot of writers,
- Especially John Steinbeck and Vladimir Nabokov.
- And then you have Dixon Pencil Company.
- They're responsible for the Dixon Ticonderoga.
- It's an icon.
- It's what people think of when they think of a pencil and
- What they think of when they think of school.
- And the pencil is really a thing
- That I think the average user has never thought twice about
- How it's made or why it's made the way it is because it's just
- Always been that way.
- In my opinion, there's nothing that can be done to make the pencil better than it is. It's perfect.
