is suprisingly devoid of all information on the hole punch, as is file-cards
in my library
. What little information I could glean
can be found below.
: Charles B. Brooks
patented the "Ticket Punch
" in the late 1800's. Though not the first hole-puncher, it was the first to be patented and the first to incorporate the "clippings" cannister.
How It Works
: As bitter_engineer
notes, the hole-puncher works much like scissors - by shear
ing two peices of metal
together. In this case, though, it is a circular shape
, not a straight bar as scissors are. They are usually used to put holes in paper so they can fit into various binding devices
Because of the shearing method described above, a long handle is usually necessary to provide enough leverage to brute-force your way through several sheets of paper. The energy required to punch through paper increases exponentially with every sheet (at least, it seems that way). Of course, this is why hydraulic and electronic punchers were invented.
: There are literally hundreds of different types of hole-puncher, so I will list the major categories. Depending on design and manufacturer, hole-punchers can punch anywhere from one to hundreds of sheets of paper at a time, and some can punch things such as sheet metal
, et al
Fun Hole-Punch Phrases!
- Singe-Hole Punch - Range in size from pocket- to industrial-strength desk mounted. Resembles a stapler. Punches a single hole.

- "You do the actual punching by pulling on a big lever and abusing your mechanical advantage." - Bitter Engineer
