>The pencil-sharpening machine “Jupiter” is one of the most famous mechanical pencil sharpeners of its time. Even today, a hundred years after its patent application, it is not on the scrap heap. Quite the reverse: more and more people like to have this impressive piece of early German engineering skills on their writing desks.

It goes back to a time when the industrial production started. It was the time when the label “Made in Germany” was a synonym for high-quality work. Not only because of this, was the machine exported to the whole world. - If you think about it properly how many ´Jupiters` are still existing today, more than 50, 80 or even 100 years after their production and after two world wars, then it does quiet impress. The mechanical pencil sharpeners, which are sold these days, are – with some exceptions (El Casco!) -  only made of plastic and stop working after the tenth pencil. In 50 years, nobody will know about them. Nevertheless, the ´Jupiters` will still exist! Probably the advertising slogan “the pencil sharpening machine that survives its owner” was right in most of the cases!

Quiet interesting is the fact that the Jupiter had its triumphal march all over the world although there have been many similar machines of competitors.

The time has come to dedicate this machine an abstract. I was able to collect many copies and information, which I would like to impart to you with the help of this brochure.

In 1987, I started to collect pencil sharpeners. I was able to collect more than 4400 pencil sharpeners, including about 200 pencil-sharpening machines. I own four different ´Jupiter` and I `ve got two similar working models: two SB, one ´Vindobona` and one ´Kastro`.<
