Als „[t]he finest pencil sharpener ever made for draftsmen“ bewarb J.S. STAEDTLER Inc. in Hackensack, New Jersey (USA), den damals neuen Kurbelspitzer 5700 D, dessen besonderes Leistungsmerkmal darin bestand, die Mine auf einer Länge von gut 6 bis 19 mm freizulegen1. Damit wurden dann auch Spitzen wie die hier und da gezeigten möglich. – Die Vorderseite dieses Faltblatts, das aus einer Blechdose stammt und etwa 60 Jahre alt sein dürfte, machte Reklame für den Farbstift MARS-LUMOCHROM, der mit einer gefährlichen Spitze auftrat.
Danke an Sola für dieses Faltblatt!
- Soweit ich weiß, gab es noch einen 5700 (also ohne „D“), der das nicht konnte und zudem nur drei statt sechs Backen in der Stifthalterung hatte. – Ein Kommentator bei pencils and other things berichtet, dass der 5700 D außerdem den Minendurchmesser auf 1,5 mm verringert.↩
You’re very welcome :) I actually think the paper inserts are more thrilling to hold in the hand than the pencils themselves – it’s just so amazing to see they survived intact after all these years. I even love the tissue paper protecting the pencil ends in old Schwan Stabilo tins ;)
Yes, you’re right – in some cases the paper inserts (as well as the whole packaging) is really more exciting than the pencils. The effort spent for the packaging back then is amazing: paper, printed on both sides and folded to cover the pencils, cardboard strips to separate them, small pieces of styrofoam to protect both the pencil points and the packaging and of course the inserts which advertised other products or informed about hardness grades etc.
This is a great sharpener. I have some more images here; http://bit.ly/1KwX0UH
including an image of the resulting point. Thanks Sola for the artwork compliment also!
Wow, your photos are great – thank you for sharing! It is clearly visible that the 5700 D reduces the lead diameter. – Your 5700 D is in remarkable good condition!
Thanks! When I got it it was covered in a grimy oily residue- like that which collects around places where food is fried, but after a good clean it came up beautifully. Maybe the oily grime protected it? The blade is mint, though. Wonderful quality German engineering.
What a find! Truly a gem and a piece of luck.
Gunther! Hello again- Something else just turned up- very strange. It’s a Koh-I-Noor 993 hand crank desktop 2mm lead shaper and it makes a 2mm lead into a perfect wedge. I have never seen one before. It has an ingenious cam gear system that engages, lifts, flips and drops the whole pencil as you crank it, over and over again, until the wedge is formed against the grinding wheel. I put up some images here-
