Wopex vs Noris

Facebook

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.

A broken Wopex

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

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 objective [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 … Continue reading.
  • 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.

Is this it?

This is not a Noris and a Tradition.

I’ve started my search for good coloured pencils, i.e. coloured pencils that are suitable for writing, many years before I started this blog. Eventually, my dissatisfaction with coloured pencils led me to coloured leads for mechanical pencils – though marginally better than coloured pencils coloured leads aren’t great either and the only hard ones I found so far are so poor you can’t enjoy writing with them either.

…but then Lexikaliker gave me new hope with his article about the Paperworld 2015 and his confirmation that you can use the new Wopex coloured pencil, the Noris colour, for writing. An extruded lead might have very different properties – maybe….

…maybe this is it. Maybe this is the holy grail of colour pencils!

Two days ago, on Tuesday, I ordered a pack of six Noris colour from eBay and they have arrived this morning, two days later. It really has been a great stationery week for me. Earlier this week I got a package from California and this morning I got one from Canada as well as the Noris colour mentioned earlier. So many things to try out.

I hope my journey of many years to find a nice coloured pencil, suitable for writing has come to an end. I will report soon.

How to sharpen a Wopex

After Pencil Revolution’s Wopex post and the following discussion on how to sharpen a Wopex: a photo of a Deli 0668 sharpened Wopex.

For many months now I have hardly ever sharpened my Wopeces with anything other than a Deli 0668. For that purpose I have one Deli 0668 at home and one in the office. The 0668’s angle of 20° is more suitable for the Wopex than the more acute angle of ~17°-18° the Deli 0635 will produce.

One warning though, the hardness of the Wopex can make the auto-stop fail. If you notice that the sharpener doesn’t stop, release the pencil holder (back to it’s original position) to avoid more of the pencil being fed further towards the burr cylinder. To finish the sharpening process just keep turning the handle until there is no more resistance .
