David Paccia has posted a video on how wooden pencils are manufactured over on his David Wasting Paper blog. Almost from the beginning I’ve used mechanical pencils because they keep a sharper line (or consistently tighter line), but when you read through David’s blog, there is still a great many artists that use the good ol’ #2.
Anyway, here’s the one he posted. I’m more impressed with the engineering that went into the manufacturing process.
He’s also posted videos on how coloring pencils, pencil sharpeners and retractable pens are made.
