Staedtler Mars Duralar and Dynagraph 

Here are some photographs to complement Gunther’s post on the Mars Duralar @Lexikaliker. I was thrilled to find that the pencil Yves Saint Laurent was holding in his hand looked exactly like the Duralar I discovered many years ago in Montreal! However, as the Duralar is specifically intended for use on drafting film, it is not very pleasant to use on paper (it drags horribly). So what exactly is YSL doing with this pencil? 😅

And then here is its successor, the Dynagraph. Thanks to Gunther’s post I now know that the lesser numbers on both the Duralar and the Dynagraph denote the softer grades.

In the Dynagraph there is an interesting logo saying “PROFILM”, which I thought was an industry designation of some sort at first but turns out to have been a trademark filed by Staedtler for its own pencils.

For a more in-depth look at how the Dynagraph performs, please refer to this classic article at Pencil Talk.
