Pentel’s Orenz is a mechanical pencil I use often, but I haven’t had the pleasure of using another one of Pentel’s pencils yet: the Graphgear.
The Graphgear’s design is great. I especially like the retractable sleeve, activated via the clip. The grip section, knurled metal with rubbery dots, officially referred to as Latex-free grip ‘pips’, and lead hardness indicator, as well as the overall construction are also amazing and show a nice attention to detail.
The lead that came with the pencil doesn’t seem to be all HB. The lead from the 0.5 mm pencil is so much softer than the one that came with the 0.4 mm pencil.
I will certainly enjoy using the different lead diameters and retracting the sleeve when I have finished writing… When I write a lot in one go I will probably still want to use a sliding sleeve pencil out of convenience, i.e. to always have the right amount of lead looking out of the sleeve.
If you read Bleistift blog regularly you might have noticed that I really like the Pentel Orenz. I think it’s the best sliding sleeve pencil since Staedtler’s Microfix.
The sliding sleeve works well and the pencil’s design is great, too, but unfortunately there is one weakness in the design that caused one of my Orenz mechanical pencils an issue: The metal clip is very close to the push button and there is only a very narrow strip of plastic to hold it in place. This narrow strip of plastic is will have to bear the brunt of any outward pressure the springiness of the clip cannot handle.
If you regularly clip the pencil onto slightly thicker pockets (or notebooks etc) the plastic will weaken over time and will eventually break off. In my case I regularly carry the Orenz in a pen pocket on my jacket. The pen pocket is not that thick, but apparently thick enough to cause this issue.
If you are squeamish please look away, the following photos, showing pencil mutilations, are not a sight for the faint hearted.
When the plastic from my Orenz broke off I didn’t initially notice as I was in a meeting. I just noticed that, when holding the pencil, the clip seems to be very loose.
Some closer inspection revealed the true horror and damage, though.
Here is a comparison how this looks like on an undamaged Orenz.
For many years there hasn’t been much going on in terms of new Caran d’Ache mechanical pencils. There is a lot of choice when it comes to ballpoint pens but there wasn’t much to look at in terms of affordable (<£50) mechanical pencils (there are unusually many in the ‘above £500’ range, though).
In recent years this changed to some extent with the 849 mechanical pencil being available in a few new colours and editions, e.g. Black Code. There are, however, not many shops here in the UK that actually stock these.
Today a new pencil joined the Caran d’Ache offering, available in a set with a ballpoint pen as a limited edition, the Set Fresher.
I am happy to see more mechanical pencils from Caran d’Ache, even though it is basically just the same pencil in different colours. I wish they’d do something else, e.g. offering a 0.5 mm version, but for now, just seeing more colours are a nice change.
Caran d’Ache seems to be starting the different colour limited editions game for their mechanical pencils and lead holders, or maybe not starting it but taking it up a notch, while Lamy is by now really good at the ‘new colour game’. Every time I think I won’t buy another Safari they come up with more good colours: last year the re-release of the original colours, this year the beautiful strawberry and cream colours, with matching clip etc.
Kaweco is also really good at this, with a mix of happy affordable colours and more posh looking ones that are slightly more expensive.
In terms of new innovation there have also been some news.
The new Kurutoga Dive is not only rotating the lead like previous versions, but is also advancing it. It is a capped and a limited edition. I wonder if the cap is there to protect the mechanism when not in use. Maybe the front is not as sturdy (in the current version) as previous Kurutogas with less complicated mechanisms. If that’s the case there might be a regular version without a cap in the future. This thought might explain why this is a limited edition: maybe they want to see first how this mechanism fares in the real world, or the manufacturing process isn’t automated enough for mass market production and some manual labour is currently involved in assembly which doesn’t make it quite mass market ready yet….

Today: a look at the Faber-Castell Grip 2011 mechanical pencil. Many years ago I bought a gel pen from the 2011 series. Unfortunately Faber-Castell stopped this gel pen and their gel refills, but there are good alternatives available.
Just like the 2001, the Faber-Castell wood-cased grip pencil, the 2011 has a triangular design with rubbery grip dots and I have read in the past that this series of triangular gip-dotted pens was a big success and saved Faber-Castell from many headaches.
Availability and price
I paid around £10 for my grass green version at PurePens. From what I can tell these are easily available in many European counties and I have seen them in high-street stores in Germany and the UK. In the USA the situation is different: I had a look to see how much they are in the USA, but I only found one place that sells them: Amazon Marketplace – for $18.
Shape and grip
I have already mentioned the main deign feature: the triangular design with rubbery grip dots.
As always, different people buy a specific pen for different reasons. I bought the 2011 mechanical pencil so that my blue gel pen from this series has company. Other make that decision to help them write without pain: a previous colleague of mine only had items from the Faber-Castell grip line in his office. When I asked him about the reasons behind this he told me that he has carpal tunnel syndrome and that it is easier for him to write with pens from the Grip line. He only used pens from this Faber-Castell series and instead of typing on his keyboard he used dictation software. I don’t know enough about this syndrome to comment further, but it sounds as if Faber-Castell’s grip design can help people to write easier or with less pain.
Weight and the grip diameter to weight ratio
Another speciality of this mechanical pencil is the low weight, probably partly down to the clutch mechanism I will mention later. As seen in the diagram below the 2011 mechanical pencil is very much on the light side.
If you don’t only want a light pencil, but also a big grip diameter then it’s worth looking at the diameter to weight ratio. Here the Grip 2011 is near the top, with a ratio 2.5 times better than some other pencils, like the TWSBI precision. Only the the Staedtler 925-15 is doing better, thanks to its low weight and its big diameter, but it does have a slightly thinner grip diameter. The only pencil in my database with a similar grip diameter to the Grip 2011 is the Caran d’Ache 888 Infinite.
The main disappointment for many seasoned mechanical pencil fans will be the Grip 2011’s clutch mechanism: it is a very simple two-jawed plastic clutch. That’s not a problem, but many mechanical pencileers prefer a brass mechanism. Generally speaking very cheap mechanical pencils, like Staedtler’s $1 graphite 777, will come with plastic clutches, but there are also much more expensive mechanical pencils than the 2011, like the Rhodia ScRipt, that have plastic clutches.
If you want a mechanical pencil that can hold a lot of leads then the Grip 2011 might also be for you: 0.7 mm leads usually have a diameter of less than 0.7 mm. The inner diameter of the Grip 2011 is 6.75 mm. If you look at the circle packing in a circle problem you will realise that this pencil can hold a huge number of leads.
The clutch will put many potential customers off, but with it’s low wide, its good grip-ability, the above average looks and the reasonable price this pencil will have no issues finding enough customers.
A few weeks ago I received a surprise parcel from John Hall of Write Here fame. Inside the parcel were two rather unusual pens that I have been using regularly since then. It’s time to send them back soon, but before I do that I want to show you these very special pens and talk about their unusual design.
Let’s get their most exotic property out of the way first: these pens are 3d printed from graphene. With graphene not being very think (one layer of atoms) you could think of it as being two-dimensional. You also commonly read that a one atom thick layer of graphite is graphene. With that in mind I am wondering how something three-dimensional can be graphene without turning into graphite. Maybe it is a flat ‘two-dimensional’ layer rolled up with some other material in between, but in that case, does it keep graphene’s properties and are they desirable in a pen body in the first place? So many questions….
I also wonder whether creating the Cento3 pen body requires very special 3d printers so that the graphene layers don’t melt together into a lump of graphite and whether the body has some sort of lacquer on top. Whatever the answers to all my questions are, the pen that Ego.M have produced is a very special pen and as I don’t understand enough about materials science I will just go along with the claim that this pen is made from graphene.
The design’s history
The idea for this pen was thought up 20 years ago, in 2001, when Achille Castiglione and Gianfranco Cavaglia came up with a pen design using the ‘trilobate’ shape. Think of three slim pens arranged together like a three-leaved clover and connected – I hope the image below gives you a better idea than my short description.
At the time some non-working prototypes were made from wood, but the pen was not commercially produced until recently when the prototypes were rediscovered by the designer’s children and EGO.M, based in Bologna, started developing the prototypes into commercially produced pens which were then officially released in February 2021, 103 years (100 = Cento, so Cento3 = 103) after Achille Castiglione was born.
About the pen
The first thing most people will notice when they look at this pen is that the individual strands of extruded plastic filament are quite visible. On the body of the mechanical pencil I received for testing the pattern produced by the 3d printing process is much less ‘even’ than on the lead holder I got. I assume every pen is unique in this respect and if you pick another sample this might be different, i.e. another mechanical pencil might look ‘smoother’ and another lead holder might look less smooth. The uneven surface loves to attract dust which is quite visible if you enlarge the photos.
The next thing to notice is that for their length and diameter the Cento3 pens are quite light. In the diagram below you can see that compared to some of the mechanical pencils we looked at in the past only slim and plastic-y mechanical pencils and tiny mechanical pencils are lighter than the Cento3 mechanical pencil.
Amateurs like me often like heavy pens as they give the user the feeling of being more substantial and of higher quality, but professionals actually like light pens. It makes sense to use a light pen that isn’t tiring when you use it all day long.
Mechanism and ageing
I was not able to figure out what kind of mechanism is used in the mechanical pencil as I don’t see a non-destructive way of getting to the mechanism. I assume the 3d printing of the body is done directly on the mechanism.
Pens change over time. One example is the beautiful surface of the Lamy 2000. Over time it becomes more and more smooth and shiny. I am not sure how hard the filament is that was used to print the Cento3, but there is a good chance that over the years the surface might become more and more smooth. This is just a guess, but it might change the character of he pen over time.
The weight and shape make the pen surprisingly comfortable to hold and use. The 3d printed structure provides a good grip when you hold the mechanical pencil. Many mechanical pencil users rotate the pen automatically and even subconsciously to make the lead use up more evenly. This is slightly more difficult with the Cento3 compared to a thinner pen, but it is possible without hassle.
The lead holder
In my opinion the lead holder version of the Cento3 feels much posher than the mechanical pencil. Maybe it is down to the chrome-y front section or the more even printing of the filaments.
