The three-hole punch

Under the handle, three chisel-edged tubes drop through a stack of up to twenty sheets in one motion, and the circular offcuts fall through matching holes in the base into a small plastic tray that slides out from underneath. The holes themselves are standardized to a fault: 11/32 of an inch in diameter, spaced four and a quarter inches apart on center, a specification so widely adopted that paper punched in one office fits directly onto a binder ring assembled in another, decades apart, without either party knowing the other exists. That tray is where the punch keeps its evidence. Left unemptied, it fills with a loose drift of paper confetti, each disc a perfect circle with a faint curl where it was struck free, and the tray will hold several hundred before the punch begins jamming on its own waste. Some trays are emptied compulsively, after every use; others are left for months, and when finally opened will make the person emptying it question exactly how much paper has passed under the handle over the life of the punch. The alignment guide, a small sliding ruler along the top edge, exists to keep a stack centered but is trusted by almost nobody, most users preferring to eyeball the edge against a printed line instead. Heavy models hold their edge for years. Cheaper ones dull within a season, tearing the last sheet in a stack rather than cutting it clean, a small failure visible only on close inspection.
