Designer Yuta Watanabe has a thing about pencils— his seem simpler and more complex than the ones we're used to. Above is the Peg Pencil, his take on the mechanical pencil. It's made from a modified spring-loaded clothespin. You just squeeze its top to put a new stick of lead in. Or to make it fall out and break on the floor, ruining your chances of doing well on the standardized test you were taking.
The Peg Pencil is just the latest of Watanabe's excellent pencil creations. Check out some of his other work below.
