Faber-Castell’s erasing knife

Faber-Castell erasing knife

Today: another kind of eraser. This one has been quite useful on many occasions. One of the recent opportunities to use it was when I received dozens of printed cards that turned out to be printed with a mistake. Thanks to this ‘eraser’ I was able to ‘erase’ the mistakes from all the printed cards easily – by scratching them off the surface.

It’s Faber-Castell’s erasing knife 181398. One of its official purposes is to sharpen Faber-Castell’s charcoal sticks, but it can also be used on paper or to sharpen pencils, as demonstrated in one of Faber-Castell’s official videos (jump to 1:12).

This erasing knife has been around for 35 years. Gunther was kind enough to send me one in 2012 as I wasn’t able to get one in the UK at that time.

A broken Wopex 6

Sniff..

I guess I’m a glass half empty guy. One of my Wopex in 2H broke today. A glass half full guy would probably rejoice, now being in possession of two pencils instead of one.

Broken Wopex

I used it to open one of the fire doors at work using the pencil. Something I am sure I did with other (wooden) pencils in the past. They survived, my Wopex didn’t.

I guess the fact that it the Wopex is hard to sharpen made me subconsciously assume that it would have a high fracture strength.

 

 


Noris colour wear and tear 2

Introduction

Here’s my first follow up post about the Noris colour, the coloured pencil made using Wopex material, which has been mentioned in a previous blog post. I bought my set of six Noris colour for £2.49 (~$3.76; €3.46) on eBay. There are also sets with 12 and with 24 pencils available.

As explained earlier I have been looking for a coloured pencil, one that is suitable for writing, for quite a while now. The Noris colour is one of the best pencils for this purpose I have seen so far.

 The test

Now this is not a scientific exploration of how fast the lead will wear down, I have neither equipment nor experience, but just to give you some rough idea what I did:

  • The average normal pen force used to write the sample lines was approximately 1 Newton. I don’t know the average axial pen force. There was obviously a lot of variation as I wrote by hand – with more force being used for downward strokes. As you can see the point broke a few times. It would be great to have a pencil hardness tester, like the Elcometer, to make these tests more objective1.
  • All pencils were sharpened using the Deli 0668, i.e. with an angle of approximately 20°. The Deli was dialled back one full rotation (360°) do avoid creating a point that will break too easily.
  • The paper used was from a Brunnen – Der grüne Block (previously seen in this post)

Before

All pencils, the Noris colour, the Eberhard Faber 1410 and the Noris club 144, had an initial line thickness of 0.1 mm – 0.3 mm (vertical / horizontal variation).

 

After

The point of the Noris colour wore down the least. After one line of writing the line variation was 0.3 mm – 0.5 mm.

The point of the Eberhard Faber 1410 wore down the most. After one line of writing the line variation was 0.5 mm – 0.6 mm.

The point wear of the Noris club 144 was in the middle. After one line of writing the line variation was 0.3 mm – 0.6 mm.

Conclusion

The Noris colour performed best. Subjectively the point felt better than what the numbers suggest, but then the Noris is also the pencil that left the lightest mark. The Eberhard Faber 1410which wore down fastest left the strongest marks on paper.

Despite the light marks the Noris colour is in my opinion the best pencil for writing or marking. It is also easy to erase.


Price Noris colour: February 2015.

I bought the Brunnen notepad in August 2011 in McPaper, Schweinfurt (Germany) for €1.19 (~$1.29; £0.86).

I bought the Noris Club pencil in 2008 from Woolworths went they into administration. I don’t remember the price.

I bought the Eberhard Faber pencils in 2010. More information about them can be found in this blog post.

  1. They’re actually supposed to the the surface you scratch with the pencils, not the pencils themselves. I guess I should either start a Kickstarter (think potato salad) to try to get my hand on a pencil hardness tester or try to build my own one. []

Happy Birthday… 8

Happy Birthday Mars plastic eraser!

Mars plastic

You’ve helped us out of our misery for 50 years.

To celebrate this occasion there’s an anniversary edition

  • of the eraser (Art. no. 526 50BK3A)
  • of the single hole sharpener (Art. no. 510 10 PR1)
  • and of the double hole sharpener (Art. no. 510 20 PR1) …among others.

To the next 50 years!


I’d like to thank Mr Schindler from Staedtler for sending me the free samples that can be seen in the picture.

You can read more about the wedge sharpener in this blog post and more about the the stick version of the Mars plastic in this blog post.

 


Pilot S20, 0.3mm, dark brown 7

 

s20-bodyHow could I resist… I never had much of a chance, did I?

…not with Gunther touting his readers with his beautiful S20, again and again and again.

I gave in…

If you click to enlarge you will notice tiny dents that must have occurred during manufacturing

…and bought the S20 in dark brown and in 0.3mm from WAKU1(Japan Store) for £13.52 (~$20.80; €18.20), including postage. I got it twelve days later. A great price, especially when keeping in mind that it costs more than twice as much in the UK (because it is imported) and you will have problems finding the 0.3mm version. I bought from WAKU1 in the past, but more about that in a future blog post.

The wood of the pen is beautiful and reminds me of the ONLINE All Wood Marone.

s20-f

Pilot is a bit optimistic though, offering an F in their lead grade indicator. Is there an 0.3mm lead in F? When I see F it’s usually for 0.5mm.

Please let me know if you know of a 0.3mm lead in F – I do prefer harder leads, so F would be great, even though I have to say the 0.3mm leads you get with many Faber-Castell pencils are a bit too hard and too light for my taste.
