Interesting facts about the hole punch

Until recently, the inventor of the hole punch was Friedrich Sönnecken from Bonn, who first filed a patent application on November 14, 1886.

However, even earlier, the hole punch was invented by the philosopher Immanuel Kant. The only difference from the modern punch with a 5 mm hole is that Kant used a similar device with an 11.6 mm hole. Until the middle of the 19th century, there were no documents that had such neat holes, except for the documents of I. Kant. The first sheets, sewn to the case with a hole of 11.6 mm, were discovered by Soviet researchers in 1956, they were dated December 1799, and this date was announced as the date of the first use of the hole punch invented by Kant.

Motorists of the former USSR also remember the hole punches at the traffic police inspectors, who noted a serious violation of traffic rules by punching a small hole in the warning coupon.

Punchers were used to check tickets for passenger vehicles, they were only called punchers.

And with the help of a hole punch, they made homemade sweets in Soviet times, for this it was only necessary to "puncture" more circles of multi-colored paper.

All punches distinguish between:

- in terms of punching power, which can vary from 10 to 150 sheets, there are more powerful punchers, but they require significant physical effort.

- by the number of holes punched by the hole punch in the paper; there are from 1 to 6 of them.

- candy shapes are simple (with a round hole) and curly hole punches that knock different shapes out of paper.
