The sliding sleeve and the Pilot Color Eno 4

Comparison of force needed with different sliding sleeve pencils

Comparison of force needed for different sliding sleeve pencils

Recently I ordered a set of seven Pilot Color Eno mechanical pencils. One reason why I bought them was that I wanted to try them for a long time: Last year I asked Fudepens to put one for me aside, so that I can get it when they get the Orenz again, but somehow they didn’t get more Orenz pens and postage-wise it wasn’t worth ordering the Color Eno by itself.

Another reason was that they were very cheap. On eBay I paid $19.99 (~£12.80; €18.20) for seven Color Eno pencils and seven packs of coloured leads – including free postage. I ordered them on 25 July and already got them on 31 July, despite them having had to travel around the globe from Hong Kong to the UK.

Sliding sleeve and coloured leads

The reason why I wanted to try the Color Eno for a long time is its sliding sleeve, more about these in one of my previous blog posts ((I thought I found out about the Color Eno on Lexikaliker’s blog, but couldn’t find it when I looked again. )). I sometimes use coloured pencil leads at work. One of my dedicated pencils for coloured leads was a Faber-Castell Grip Matic (the auto advancing kind). If you know how to use it it was fine, but every time a colleague would grab it to write with it they would break the soft coloured leads and generally clog the Grip Matic up. An easy to handle mechanical pencil for coloured leads did therefore sound like a really good idea.

First impressions Color Eno

My first impressions of the Color Eno are not so positive. It is a nice pencil in itself, with such a close similarity to the Super Grip1 (both from Pilot), but the feature I wanted it for, the sliding sleeve, doesn’t work for me. It does work for me when I use the Super Grip, though2. The sleeve doesn’t slide back when I write. It might work for others, especially if you hold your pen in a vertical or near vertical position. My first idea was that this is because or a combination of force needed to push the sleeve back and sleeve thickness. After comparing the Color Eno to other sliding sleeve pencils I think the thickness of the Color Eno‘s sleeve doesn’t really matter that much.

The Color Eno's sleeve doesn't glide back so after a while you write on the sleeve. Not so with the Orenz.

A little warning regarding my chart: I have neither the training, nor experience, nor the equipment to take these measurements properly, so you better take these measurements with a pinch of salt, or even better with a whole lorryload full of salt.

The Pentel Orenz works with 0.2 mm leads. The sleeve has an other diameter of ~0.6 mm. You need less than 1 cN to slide the sleeve. You might have read from Lexikaliker that the Orenz will be available in Germany from autumn 2015. The good news is that the Orenz will officially come to the UK, too. From January 2016 it will be available in 0.2 mm and 0.3 mm.

The Staedtler Microfix works with 0.5 mm leads. The sleeve has an other diameter of ~1 mm. It is not being manufactured anymore. You need less than 5 cN to slide the sleeve.

The Pilot Super Grip works with 0.5 mm leads. The sleeve has an other diameter of ~1 mm. You need less than 2 dN to slide the sleeve. My version was bought nearly 15 years ago, so I am not sure whether the current version needs the same force to slide the sleeve.

The Pilot Color Eno works with 0.7 mm leads. The sleeve has an other diameter of ~1.1 mm. You need about 6 – 8 dN to slide the sleeve (different force needed on the different versions I have of this pencil).

The Caran d’Ache 844 works with 0.7 mm leads. The sleeve has an other diameter of ~1.05 mm. You need about 1 N to slide the sleeve.

  1. It didn’t realise this when I saw pictures of the Color Eno. I only noticed it now that I have it in my hands []
  2. The Super Grip must have been the first mechanical pencil I bought after I arrived in the UK in 2001. It has been available since the 1990s. The Super Grip Neon was released in 2014. []

Why did the sliding sleeve disappear? 15

Getting to know the sliding sleeve pencils again

Thanks to Lexikaliker whetting my my appetite and with some help from Shangching I got my hands on a Pentel Orenz. I have been using it for a few weeks now and like it very much. A blog post will follow, hopefully, once my time permits.

One of the nice features of the Orenz is the sliding sleeve. You don’t have to keep manually forwarding the lead to be able to keep writing. Instead the sleeve will slide back while you write until there’s no sleeve left. Only then do you have to forward the lead – and the sleeve will slide out again.

Retractable vs sliding sleeve

Just to clarify, when I write about a sliding sleeve I mean a one that slowly slides back while you write. The other type, a sleeve that is either completely out (for writing) or completely in (for transport) is the type I call a retractable sleeve. I hope these labels are correct, I’m not sure, but this helps to avoid confusing both types. Please let me know if the names I use for the sleeves are wrong.

In the past

The sliding sleeve is nothing new. The Staedtler Microfix1 I used in school could do that. At that time Staedtler sold mechanical pencils with three different types of sleeves: fixed (F models), half slide (HS models) and full slide (S / SL models), but as far as I know the sliding sleeves have disappeared in the late 1980s.

Why are they gone?

Unfortunately these types of mechanical pencils are quite rare. I can see the advantage of a fixed sleeve for an engineer who needs his or her pencil to create precise drawings, but these days that kind of work is done on a computer – so why did the sliding sleeve not come back? In my opinion it provides a much better writing experience than a fixed sleeve mechanical pencil.

You can still get mechanical pencils with sliding sleeves. One example is Caran d’Ache’s 844 pencil, mentioned previously, but the 844’s sleeve is quite wide meaning it will prevent full contact of the lead with the paper – the sleeve is in the way when you are writing.

You can still buy new old stock (NOS) of the Microfix, but it’s not cheap (If I were to win the lottery this weekend I’d buy the whole set).

Do you know of any nice sliding sleeve mechanical pencils still available?

  1. Available from 1977 until 1988. []
