How have I missed this!!??! In MechFrankenPencil I suggested the idea of a Rotring Newton type gravity selector mechanism multi-pencil but with 3 different pencils instead of different ballpoints. Now I find out they actually made it!!!! How did I miss out?I recently chanced across the Rotring Trio-Pencil on eBay and my mind boggled.
I rushed to my Rotring catalogue, or rather “Schreibgefühl 2001 / 2002 rotring” as Rotring call it. Apparently that’s a bit of marketing speak, meaning “The feeling of writing”, “That writing feeling”, “The look and feel of writing (instruments)”, well something like that anyway.
LOOK, there, in the catalogue section “rotring Multipen”. Right before my very eyes for all these years! Blind, illiterate, idiot…clearly I am one or more of these. Man, this blog really does keep reminding me how little I know, and how much I don’t know. The shame of it all.
R 502 705 0 trio-pen, Schwarz, 3 Feinminenstifte (0,35mm, 0,5mm, 0,7mm)Oh the Germanic precision of it. They even use commas instead of decimal points, and spaces instead of commas in their numbers, reminding me just how wrong I am.
Like so much of their range, Rotring apparently stopped making the Trio-pencil quite sometime ago, but good ole eBay still has some “new old stock” available. Obviously price was irrelevant, I had to have one!
Actually mine is slightly different to the picture in the catalogue, having a silver push top button rather than a black one like the catalogue.
The card box that the plastic presentation case comes in states “Sanford rotring GmbH” so it dates after 1998 when Sanford took over Rotring. It also has the old Rotring website on it, “rotring.com”. That’s long since gone. The current Newell Rubbermaid (Sanford) website doesn’t even list the Rotring brand anymore, just Papermate, Parker and Waterman of their “pencil” companies. I’m fairly sure that the website did list Rotring a year or so ago, when I last looked, so who knows what’s going on.
Printed on the body is 0.35, 0.5 and 0.7. Just like the Newton, there is a gravity selector system, so whichever size is held upright is the tip that comes out when you push the top button down. 10 clicks of the push top ratchet lead advance mechanisms extends 6mm of lead, irrespective of lead diameter.

You retract the pencil tip by
pushing down the small lever that sticks up in the pocket clip. The spring loaded mechanism then retracts the tip back up inside the body.There is a small eraser under the top cap. Leads are refilled by unscrewing the body to get to the three pencil units. The grip section is a slightly wider diameter than the rest of the body.
Dimensions – Length 138mm, 10mm diameter body.
The Uni Auto Eraser, model EH-100P, is made in Japan by Mitsubishi Pencil Company Ltd. Essentially it is a basic push top ratchet mechanical “pencil” that propels a 5mm diameter eraser rather than a piece of pencil lead. The mechanism really does feel and sound quite like an ordinary mechanical pencil mechanism.
From my engineering and general office user background, I’ve traditionally mostly used medium and harder grades of lead, in the B to 2H sort of range. With these grades the Uni erasing power is adequate, but not exceptional. It doesn’t smear the pencil marks, but doesn’t quite seem to erase them as completely as some other erasers do, for example my trusty 





I’ve ended up with a few Conway Stewart Nippy No. 3’s, all green or blue marble with black veins. As I’ve said before, they look really great. Deep lustrous colours that come from way down inside the plastic. Beautiful gold plated metal trims. Fantastic! Most of my co-workers don’t really know about my “pencil-habit”, but the Nippy produced a few comments, “Wow, that’s a fancy looking little pen”(sic). The lights at my work really seemed to accentuate the marbling effect, I just wish my photos could do them justice.
Well lets get my prejudices out of the way first. I mean aesthetically there’s the big grip thing, and it’s a rubber grip thing, then there’s the barcode printed straight on the body, the monstrous clear angular document clip, the whole thing is just yuck, yuck, blah! (That’s an official technical reviewing term.) But, they have also tried to do “something”, with the spiralling silver swirl pattern printed on the body to tie in with the twisting flex fit grip. OK, lets not dwell on it, move on.
This is actually a vanishing point type pencil, like the Pentel Graphgear 1000 or the Pilot Vanishing Point mechanical pencils. You press down on the top of the document clip and the spring loaded system retracts the tip section back up inside the body for travel and pocket safety. 

What is “Maki-e”? Well I’ve seen the term used quite a lot in reference to those fountain pens that are beautifully decorated in a Japanese or Oriental style. A quick bit of online browsing informs me that maki-e means “sprinkled picture” in Japanese and it is a method of decorating lacquerware with gold, silver and other powders. Originally of course the lacquer was real tree sap lacquer, the gold was real gold, and so on. Naturally if you have a few extra dollars burning a hole in your pocket you can buy “real” maki-e, but the rest of us generally get modern versions made with modern materials, modern manufacturing processes, etc which combine to produce a price more affordable to the average pencil collector like myself.
The grip on this pencil is fairly good for something without any special grip enhancements. The resin body is smooth and shiny but the material is not slippery. It’s also about average weight for a multi pen, balanced fairly neutral, but a little towards the top. The pocket clip is quite strong, but easily usable. The gold trims are not particularly golden, perhaps a rather low gold content in the alloy?
The instruction leaflet is in Japanese, but the diagrams are clearly understandable. However, there is no diagram for the multi-pen! Fountain pen, mechanical pencil, rollerball and so on, but not the multi pen. This really annoys me, because multi pens need proper instructions on how to disassemble them for refilling , etc. It’s certainly possible to ruin them if you don’t know what you are doing. I have figured this Platinum one out by experience with other brands and by looking at the diagrams for the other pen modes, but still, it really is second rate not to include the instructions.
