My new Orenz reminds me of a summer probably about 30 years ago. I’m playing Snoopy and the Red Baron1 (borrowed from a friend) on my Atari VCS 2600 – and there’s also a red, mechanical Snoopy pencil involved2. I even think that the Snoopies printed on the pencil were quite similar to the ones you can find on the Orenz.

I bought this ‘Vintage Peanuts – Snoopy’ pencil from a Taiwanese eBay seller and paid £11.65 (~ $18; €16.35) – £8.15 for the pencil and £3.50 for postage.

A use for the Orenz

Like all Orenz pencil it is great for someone with small handwriting or if you need to make small annotations in documents.

This is actually my third Orenz. My blue one arrived in a letter from America, thanks to Shangching‘s generosity and my white one was bought from Amazon for £4.23 (~ $6.50; €5.90).

Peculiarities of 0.2mm leads

Unfortunately there is one of the problems you will find with 0.2 mm leads that you probably won’t encounter with more traditional mechanical pencils. When I got the white Orenz and tried to use it for the first time the 0.2 mm leads are so light, the static charge of the plastic barrel made them stick to the inside barrel of the pencil and it wasn’t possible to get the leads to forward the normal way. In the end I had to take a lead and feed it though the sleeve / front of the pencil. Once that sleeve was used up the pencil was clogged up, too – but it was then possible to unclog the pencil by disassembling it. Not great, but still much better than the kind of mess I experienced with a Rotring Newton.

  1. I still remember the title screen music []
  2. Now that I think of it I think it might have been a Zebra pencil, but I am not sure. The pencil should still be in my mothers house so I’ll check next time I’ll be there. []

Pimp my Rotring rapid PRO 0.5

This is a follow-up blog post to my earlier blog post about the Rotring rapid PRO 0.5.

The Rotring rapid PRO is a stunningly beautiful mechanical pencil, at least the black version is …for my taste. As you might remember the sliding sleeve was the worst performing sliding sleeve I have seen so far.

The purpose of a sliding sleeve

The main purpose of a sliding sleeve is, in my opinion, to slide back while you write so that you can keep writing without having to press the button / use whatever mechanism there is to advance the lead.

If the sliding sleeve doesn’t slide back easily you might as well got for a retractable sleeve, one that is either all the way in or out. This make the pencil pocket safe and allows work that is more suitable for drafting purposes, too.

On the unmodified rapid PRO 0.5 you had to use a force of about 1.2 N to get the sleeve to move – far too much to make the sleeve slide back automatically while you write.

The sleeve

Pimp my sliding sleeve

Having never explored how the sliding sleeve mechanism works I assumed ‘simple’ friction is responsible for the force needed to slide the sleeve. The problem is: I thought it’s the friction between the sleeve and grip section holding the sleeve (the grip section can be seen on the left in the first picture). To reduce the friction I took the sleeve out and started removing material from the sleeve on my Spyderco Sharpmaker. This made the sleeve thinner, something I had hoped would reduce the friction, but after a while I noticed that this treatment didn’t help making the sleeve slide easier at all.

Trying to reduce the friction – the wrong way: the sleeve on a Sharpmaker

I then figured out that the friction holding the sleeve in place must be caused by the white plastic holder at the bottom of the sleeve. I started using the file from my Swiss Army knife1 to remove some of the plastic, i.e. making the plastic holder narrower, but that took too long, so in the end I just cut bits of the plastic off with the knife.

This time it worked. Great!

From 1.2 N to 0.2 N

The result: You now only need about 0.2 N to slide the sleeve of my rapid PRO, which makes it suitable for writing without having to advance the lead all the time. This is an amazing result – because of the bigger lead diameter you can’t compare an 0.5 mm sleeve directly to the 0.2 mm sleeve of the Orenz. Just the friction caused by the 0.5 mm lead in the rapid PRO’s sleeve (i.e. just these two parts, ‘outside’ the pencil) means that you need 0.1 N just to slide the sleeve down the lead – that’s without the additional force needed to slide the sleeve within the pencil barrel/ grip section.

If I’d have to do it all again I obviously wouldn’t make the metal sleeve narrower. It made the sleeve a bit more wobbly, but it is not really an issue. It is certainly still less wobbly than a Kuru Toga or Muji’s flat clip mechanical pencil.

That's one small scrape off [a] sleeve, one giant leap in the friction chart.

More about the Cloud Book in the blog post, I’m still using it regularly.

  1. Fun fact: I got this knife from my godfather in the 1980s and I believe it is the same model as the one that the astronauts used on the Space Shuttle, just mine has a cork screw instead of a screw driver. []

M+R 0981 sharpener 3

I recently got the M+R 0981″crank-style sharpener” from Lexikaliker.

The 0981 is one of the Möbius und Ruppert sharpeners that is not manufactured by M+R – according to their website it is produced by premium partners in Asia. I’m not sure whether this means that M+R designed this sharpener or whether they just put their name on an existing sharpener. In any case, it does look very similar to the Dahle 133, as discussed by Lexikaliker.

Overall this is a really nice sharpener.

No bite marks

It doesn’t leave bite marks on the pencil, that’s a big advantage – or in my case even a necessary requirement. I don’t think I’d use a pencil sharpener regularly if it leaves bite marks – however good the sharpening mechanism might be.

The point

The point it creates is quite nice and concave. Concave points look good, but I find measuring the angle more difficult. When I try to measure the 0981’s angle using my traditional method I get an angle of 20°. When I measure the angle on a computer I get an angle of slightly more than 21°. In any case the point produced suitable for most purposes, you can compare this angle to other angles on my sharpener page.

Other features

The crank features a dial, not uncommon for this kind of sharpener. If you dial all the way to the left you get a ‘full’ point, but you can also create a ‘flat’ point, more suitable for coloured pencils if you set the dial to the right. Any setting in-between both extremes is also possible (the difference between both settings is about 3.5 full turn of the dial (1260°)).

The drawer is of course removable, for emptying the waste created during sharpening. The cutting mechanism is removable as well.

I tried to sharpen a Wopex in the 0981, but the auto stop doesn’t work with the harder material encasing the Wopex lead – this is common for crank sharpeners.

Price and availability

When you search for this sharpener on the internet most pages you can find seem to be from Japan. I assume this means that this sharpener is more commonly available in Japan. You can however find some sellers in the West. In Germany you can get this sharpener for €10 – €15 (~$11 – $22: £7.50 – £15), which seems good value for money.

Rotring rapid PRO 0.5 2

During my hunt for the perfect sliding sleeve pencil I came across the Rotring rapid PRO 0.5. I’m looking for a sliding sleeve that slides back easily enough so that I can keep writing while the lead is worn down – without having to advance the lead all the time.

I bought the rapid PRO for £18.95 (~$29; €26) from Pilotfishpens on eBay. It usually sells for about £25 in the UK.

A well reviewed pencil

Having bought it because of its sliding sleeve I was aware of and have read reviews of the pencils, but every blog post or review pays attention to very different details, so if you are interested in this pencil please look at the other reviews (see list at the bottom of this blog post), they might contain more of the information you might be after – oh, well infinite diversity in infinite combinations.


As far as Rotring mechanical pencils go, this is a fairly new model. It has been released many years after Sanford / Newell Rubbermaid took over. You can find more of my thought about how Rotring changed since Sanford / Newell Rubbermaid took this company over in my blog post about the Rotring Newton.

 Looks – stunningly beautiful

I read Dave’s review and I have also seen reviews of other Rotring pencils with a similar surface, but I didn’t expect such a good looking pencil! The finish, matt but also reflective, is absolutely beautiful. I tried to capture it using HDR, a technique Lexikaliker has used many times on his blog, but the photo doesn’t show the real beauty of this pen in any way.


Other observations

The knurled grip area is metal, but the knurling is so fine, dust and small particles will stick to it. Nice looking, good to grip, but not easy to clean.

The lead it comes with is (for my taste) ridiculously soft. I like harder leads. This one is nice and dark, but gets worn down very fast.

The red ring is plastic, so the colour wouldn’t come off, as is common on Rotring Tikkys. Most parts are metal, but some parts, like the red ring and the screw threads, as well as the mechanism holding the sliding sleeve, are plastic. I wonder whether the pen will one day fail because of some cheap plastic parts, as was the case with my Rotring Newton, which didn’t last long at all

Sliding sleeve

The sliding sleeve, the main reason why I bought this pencil was a disappointment. You need even more force to slide this sleeve than you need to slide the sleeve of the Caran d’Ache 844, the worst performing sliding sleeve in a previous comparison. This renders one of the main advantages of a sliding sleeve, not having to forward the lead all the time, useless.

I really love the look of this pencil, so in the end I made a minor modification to make this pencil work for me (more about this in another blog post). The diagram shown here, comparing the force needed to slide the sleeve of different pencils, does however represent an off the shelf, unmodified Rotring rapid PRO 0.5.

Excuse the image quality, I took the photo with my mp3 player.

A beautiful pencil. Not cheap, but also not one of the really expensive ones. I love the look. The sliding sleeve is too stiff for my taste, but can be adjusted if you don’t mind voiding your warranty. I hope it will last a long time and won’t fail because of some of the plastic components used.

Wopex vs Noris 8


After a bit more than three years and many posts later the Bleistift Facebook page reached 100 likes this week. Well, I have to confess that I cheated and invited some of my friends to like the page, anyway: next aim: 200 likes by 2018, but that will be more difficult, as I have already invited some friends plus some people will probably unlike the page over the next three years. We will see…

Wopex vs Noris

Anyway, onto the real blog post:

You might remember the blog post about the Staedtler 501 180 sharpener. Staedtler’s rotary sharpeners start with 501 and their Wopex pencils are associated with the number 180. Despite this sharpener being officially available in the UK I didn’t come across it yet, so I keep using my Deli to make a great Wopex point. Here’s a comparison of a Wopex, sharpened in a Deli 0635 and a Noris, sharpened in the same Deli.
