FABER CASTELL DS75 MECHANICAL PENCIL - OLDER TYPE
파버카스텔 DS75 샤프 구형
What was the world's first full-automatic mechanical pencil?
I've discussed this issue several times as I talk about Faber Castell's TK-matic and Alpha-matic mechanical pencils.
By the word "full-automatic," I mean something that doesn't require pushing the push button.
It seems nonarguable the answer is Faber Castell's DS75 mechanical pencil.
It first appeared in the advertisement in 1981, so it's reasonable to estimate DS75 was born in 1981.
As will be discussed soon, DS75 model experienced a slight modification in its design afterwards.
DS75 model is made of a brushed stainless steel body with 14k gold plated clip and end pieces.
There are diverse members in DS family: DS05, DS15, ... , DS75 including some additional members like the Aviator model.
Obviously, different models used different material, and 14k gold plating was only reserved for the high end models.
The word "DS" refers to "druckbleistift," which means a mechanical pencil in German.
There also existed FH(fountain pen), RO(rollerbal), and KS(ballpoint pen) versions.
The numbering systems were different for different types of pen.
The highest models were DS75, FH50, RO58, and KS50, respectively (as far as I know) - all of them were made of brushed stainless steel and 14k gold plating.
Brushed stainless steel.
The barrel is highly glossy.

Keep an eye on the push button part.
It's a best moment to describe what modification it suffered.
Here are two advertisements of DS75.
The right one (4/81) has the photo of older model, whereas the left one (3/82) has the photo of the later model.
If I'm reading the date in the correct way, the transition took place between April 1981 and March 1982.
Did you spot the difference between these two models?
First, the cone parts show a slight discrepancy.
Contrary to the older one with a rounder cone, the later model has an angular cone.
More obvious way to distinguish them is to observe the back end.
The barrel of the later model ends right after the clip, the older model has a lengthier barrel on the other hand.
By this, the thinner part of the push button is exposed for the later model.
The 14k gold plated cone became a little bit dirty, but it doesn't bother to see its rounder shape.
The lead sleeve can be partially retracted and the lead is ejected when the lead sleeve is retracted.
