Japanese pencil sharpener brand Nakajima Jukyudo recently released Tsunago, an ingenious pencil sharpener that joins old pencil stubs together to form a new, usable pencil. The clever manually-operated sharpener joins pencils in a three-step process: First, a hole is bored into the back end of a pencil stub A. Next, the tip of pencil stub B is specially sharpened, leaving a “stepped” tip. The stepped tip is cleaned (neatness counts!) before pencil B is nested in the back end of pencil A.
