0:00:00.198,0:00:03.563 The sound is a really big part, I think,[br]of the experience of using a pencil, 0:00:03.588,0:00:07.064 and it has this really[br]audible scratchiness. 0:00:07.088,0:00:09.290 (Scratching) 0:00:10.286,0:00:12.806 [Small thing. Big idea.] 0:00:13.985,0:00:16.313 [Caroline Weaver on[br]the Pencil] 0:00:16.556,0:00:18.926 The pencil is a very simple object. 0:00:18.950,0:00:21.435 It's made of wood[br]with some layers of paint 0:00:21.459,0:00:22.975 an eraser and a core, 0:00:22.999,0:00:25.395 which is made out of graphite,[br]clay and water. 0:00:25.419,0:00:27.951 Yeah, it took hundreds[br]of people over centuries 0:00:27.975,0:00:29.651 to come to this design. 0:00:29.675,0:00:32.956 And it's that long history[br]of collaboration 0:00:32.980,0:00:35.638 that, to me, makes it[br]a very perfect object. 0:00:36.075,0:00:38.349 The story of the pencil[br]starts with graphite. 0:00:38.373,0:00:41.290 People started finding[br]really useful applications 0:00:41.314,0:00:42.925 for this new substance. 0:00:42.949,0:00:45.107 They cut it into small sticks 0:00:45.131,0:00:47.599 and wrapped it in string[br]or sheepskin or paper 0:00:47.623,0:00:49.617 and sold it on the streets of London 0:00:49.641,0:00:51.797 to be used for writing or for drawing 0:00:51.821,0:00:54.313 or, a lot of times,[br]by farmers and shepherds, 0:00:54.337,0:00:55.996 who used it to mark their animals. 0:00:56.020,0:00:57.263 Over in France, 0:00:57.287,0:01:01.441 Nicolas-Jacques Conté figured out a method[br]of grinding the graphite, 0:01:01.465,0:01:04.584 mixing it with powdered clay[br]and water to make a paste. 0:01:04.608,0:01:07.777 From there, this paste was filled[br]into a mold and fired in a kiln, 0:01:07.801,0:01:10.751 and the result was[br]a really strong graphite core 0:01:10.775,0:01:13.894 that wasn't breakable,[br]that was smooth, usable -- 0:01:13.918,0:01:17.014 it was so much better than anything else[br]that existed at the time, 0:01:17.038,0:01:20.848 and to this day, that's the method[br]that's still used in making pencils. 0:01:21.461,0:01:24.588 Meanwhile, over in America,[br]in Concord, Massachusetts, 0:01:24.612,0:01:27.660 it was Henry David Thoreau[br]who came up with the grading scale 0:01:27.684,0:01:29.770 for different hardnesses of pencil. 0:01:29.794,0:01:31.717 It was graded one through four, 0:01:31.741,0:01:35.392 number two being the ideal[br]hardness for general use. 0:01:35.416,0:01:37.966 The softer the pencil,[br]the more graphite it had in it, 0:01:37.990,0:01:40.355 and the darker and smoother[br]the line will be. 0:01:41.495,0:01:43.782 The firmer the pencil,[br]the more clay it had in it 0:01:43.806,0:01:45.816 and the lighter and finer it will be. 0:01:46.607,0:01:49.774 Originally, when pencils were handmade,[br]they were made round. 0:01:49.798,0:01:51.472 There was no easy way to make them, 0:01:51.496,0:01:54.758 and it was the Americans[br]who really mechanized the craft. 0:01:54.782,0:01:56.728 A lot of people credit Joseph Dixon 0:01:56.752,0:02:00.440 for being one of the first people[br]to start developing actual machines 0:02:00.464,0:02:04.371 to do things like cut wood slats,[br]cut grooves into the wood, 0:02:04.395,0:02:05.604 apply glue to them ... 0:02:05.628,0:02:08.439 And they figured out[br]it was easier and less wasteful 0:02:08.463,0:02:10.091 to do a hexagonal pencil, 0:02:10.115,0:02:11.973 and so that became the standard. 0:02:12.558,0:02:14.121 Since the early days of pencils, 0:02:14.145,0:02:16.210 people have loved that they can be erased. 0:02:17.942,0:02:19.510 Originally, it was bread crumbs 0:02:19.534,0:02:21.617 that were used[br]to scratch away pencil marks 0:02:21.641,0:02:23.210 and later, rubber and pumice. 0:02:23.675,0:02:26.967 The attached eraser happened in 1858, 0:02:26.991,0:02:30.948 when American stationer[br]Hymen Lipman patented the first pencil 0:02:30.972,0:02:32.354 with an attached eraser, 0:02:32.378,0:02:34.250 which really changed the pencil game. 0:02:34.965,0:02:38.359 The world's first yellow pencil[br]was the KOH-I-NOOR 1500. 0:02:38.383,0:02:39.888 KOH-I-NOOR did this crazy thing 0:02:39.912,0:02:42.825 where they painted this pencil[br]with 14 coats of yellow paint 0:02:42.849,0:02:44.782 and dipped the end in 14-carat gold. 0:02:45.442,0:02:47.016 There is a pencil for everyone, 0:02:47.040,0:02:49.447 and every pencil has a story. 0:02:50.046,0:02:54.425 The Blackwing 602 is famous[br]for being used by a lot of writers, 0:02:54.449,0:02:57.409 especially John Steinbeck[br]and Vladimir Nabokov. 0:02:57.433,0:03:00.037 And then, you have[br]the Dixon pencil company. 0:03:00.061,0:03:02.998 They're responsible[br]for the Dixon Ticonderoga. 0:03:03.022,0:03:04.173 It's an icon, 0:03:04.197,0:03:06.724 it's what people think of[br]when they think of a pencil 0:03:06.748,0:03:09.171 and what they think of[br]when they think of school. 0:03:09.195,0:03:11.409 And the pencil's really[br]a thing that, I think, 0:03:11.433,0:03:13.910 the average user[br]has never thought twice about, 0:03:13.934,0:03:16.079 how it's made or why it's made[br]the way it is, 0:03:16.103,0:03:18.047 because it's just always been that way. 0:03:19.050,0:03:21.284 In my opinion, there's nothing[br]that can be done 0:03:21.308,0:03:23.172 to make the pencil better than it is. 0:03:24.267,0:03:25.417 It's perfect.
