exploring the art and science of pencils since 2005
A special variant of the famous Mitsubishi Uni pencil.
The Jumbo-uni is 25cm long and 1cm in diameter!
The appearance and markings are generally the same as the regular Uni. Some text is different:
It really is Jumbo:
Uni pencils mention the company establishment in 1887. “85th anniversary” suggests 1887 + 85 = 1972. Is this pencil really 38 years old? Well done, Mitsubishi Pencil Co.
First unveiled at the 2010 Paperworld show and reviewed at Lexikaliker, a few LAMY plus pencils have washed up on this side of the Atlantic.
From LAMY, a firm renowned for their design capabilities, we have two-tone grey and silver triangular pencils.
The “plus” is a slightly oversize 8.5mm diameter pencil with an oversize 4mm core. The silver side has the familiar LAMY logo. It comes in HB and B grades.
The “4plus” is a jumbo 10mm diameter pencil with a huge 6.25mm core. It comes only in B, and varies slightly from the plus in having the cap completely finished.
The “Made in Germany” pencils have an amazing appearance and with dark, rich graphite cores, offer a great writing experience. The only minor thing I’ll note is that the HB and B leads did seem very similar to me.
This is a great boost for the pencil industry. To have a company with the stature of LAMY enter this market with a high end product bodes well. Just when many companies are leaving the field, we have a very savvy new entrant.
My thanks to Gunther from Lexikaliker for sending me these samples.
Let’s take a brief trip into the almost departed world of drafting by pencil. Before computer aided design (CAD), precision drawings were made by hand. Architects, draftspeople, engineers, and others, used lead pencils alongside other tools to create plans for everything from small industrial parts to immense cities.
The observations made here are probably trivialities to those familiar with the tools. Yet as an “obsolete” technology, the capabilities of drafting film and film pencils may be unknown to those of us who never experienced these products first hand, and I thought it would be enjoyable to share some discoveries.
I’ve been fortunate to be able to assemble some vintage supplies.
– Staedtler Mars Dynagraph 100 50 woodcase pencils in grade N3.
– Staedtler Mars Dynagraph 0.5mm (255 05) and 0.7mm (255 07) mechanical pencil leads in grade N2.
– Mylar polyester drafting film.
The lead refills and drafting film were purchased at retail about two weeks ago! The pencils came from eBay.
Some further notes.
The grades – N0 through N6. An old Staedtler catalogue online at leadholder.com suggests these comparisons:
N0 = HB
N2 = H
N4 = 5H
Adding information from this fascinating chart at Lowell Bueprint, we can complete the chart this way:
N0 = HB
N1 = F
N2 = H
N3 = 3H
N4 = 5H
N5 = 7H
Both the pencils and the leads have an additional logo, “profilm”. Though I own many Staedtler pencils, I have not seen this additional graphic before. This site, for example, suggests that this is an early 1980s Staedtler trademark, now abandoned.
The pencils are explicitly marked “For use on drafting film.”
The film is something I’ve been seeking for some while. I was quite happy to discover a local retailer who was willing to cut a small piece for me off of a roll. Mylar is Dupont’s trademarked name for polyester film. There are other brands, but Mylar seems to be a bit of a standard.
The photos below generally show the Mylar on top of graph paper – either 2mm vellum, or a Moleskine notebook. This is for contrast – it had to be placed on some sort of surface. The Mylar does not have any lines. It does have a milky translucence, and feels quite strong to the touch.
Observation no. 1: The erasure of Dynagraph pencil lines on Mylar is remarkable. To my own eye in direct sunlight, it seemed close to perfection. The macro setting of the camera brings one back to earth, but still, I have to say that the erasure properties of the N3 Dynagraph pencil/Mylar film/Mars plastic eraser trio well surpass the paper and pencil experience. Even the typical paper indentation that one can usually discern is absent, presumably due to the film’s strength.
Observation no. 2: The specialty lead is truly non-smearing! To the right is the misbehaving Staedtler Mars Lumograph 2H. Light finger movement causes considerable smudging. The Dynagraph leaves a nearly immutable line.
Observation no. 3: Pencil grades, even the very hard grades that behave like rocks on paper, are much more vivid on film. A 3H looks like a 3B. Take the extreme Mitsubishi Hi-Uni 10H:
It is near useless, fainter than the printed lines, in a notebook:
Yet makes a valid mark on the drafting film:
So film certainly gives an invigorated life to those 2H through 10H pencils which are very challenging to use on paper.
To summarize these basic observations about film pencils on film: Perfect erasure, no smearing, and lines appear significantly darker.
The computer isn’t going away, but I’m wondering if these properties might not be valuable to artists. And I haven’t yet noted that this “paper” is supposed to last centuries and maintain stability.
I can’t find a Mylar sketchbook for sale, but did find that David Hockney was aware of this medium. If you use this medium or are aware of other artists who use it, please leave a comment.
And while this post is engaged in a bit of a “rediscovery” of the past, let’s acknowledge those who’ve never forgotten these skills: twenty-first century architects who still work with pencil. These two have mentioned their continued use of pencils at this blog:
Otto-Walker Architects, Park City, Utah
J Mark Nelson LLC, Colorado Springs, Colorado
These products may have peaked in popularity in the 1980s, but the Dynagraph and Mylar duo still seem capable of getting a precision job done.
P.S. Please see “Zeitreise” at Lexikaliker, which shows some vintage advertisements for Duralar (the predecessor name of Dynagraph) pencils on Mylar.
These are not pencils for writing memoirs or taking scientific notes. Made by Caran d’Ache, the graphite core is water soluble. Like watercolour paint, the graphite dissolves when wet, becoming another type of medium, while remaining graphite.
The pencils, in HB, B, and 3B, have the bar code attached to a removable plastic piece:
The pencil is exceptional in appearance, with a beautiful and simple gold imprint on a matte black background. An easy sharpening cedar pencil, it really has the feel of a quality art supply.
The brush icon indicates that this is a water soluble pencil:
The cap is glossy:
I am not an artist! But even as a backyard doodler, I can see that these pencils are both capable and fun. Going over a drawing with a fine brush dipped in water unleashes nuances and shading capabilities that would be challenging to achieve with regular pencils. Or at least for me they would be!
Maybe you have tried them, or a similar product?
The growth of online stores, auctions, and selling forums has resulted in many benefits for pencil end users, including the ability to discover unusual products. Here is an example.
How many people outside of Malaysia knew that Staedtler made a red and blue pencil?
The traditional red and blue format survives, yet I’ll bet very few people would know where to find one. I suspect that in most markets, not a single brick and mortar store carries such an item.
Certainly this particular pencil is a surprise – why is it so “beneath the radar”? From a major manufacturer, it would command a market simply due to the brand.
So there are a few things different – the tradition name, usually written with the lower case t, has graduated to using a majuscule T.
The markings are also a bit un-Staedtler – no bar code, just the text, “Staedtler Tradition 118-2/3”. 2/3? 2/3 of what? And the imprints don’t seem to be of top quality.
The red and blue markings do seem to be nicely merged with the traditional tradition branding.
And finally – why the tradition line? How does this variant relate to the 110 pencil?
The Malaysian made (according to the box) pencils are a nice oversize hexagonal shape, and function well. The line seems a bit dry while richly pigmented – nicely tuned for writing. I look forward to using them.
P.S. This is the 500th post at pencil talk.
Continuing from the previous post, we open up the tin. I would say there is a lot of evidence of pride in the product:
The paper flaps have all sorts of fascinating information about the MARS line. I like the list of the “most important” products:
The pencils, finished in black, perhaps have less show than we might expect, yet still look great:
