Restoring a grenade 7

…the sharpener called grenade, not a real grenade.

Or should that be ‘How not to restore a grenade’? – you’ll see why.

The age and the name of this sharpener even fit with the current 100th anniversary of Britain’s involvement in WWI, which is being commemorated on a national and on a local level – with local museums and libraries in and around Preston (where I live) taking part.

The grenade sharpener design has been around since 18471 and is still being sold today. I got a modern one, which Lexikaliker got me five years ago when I wasn’t able to get one in the UK.

Cleaning

A few days ago I also got my hands on an old version – I was lucky enough to get one for a good price.

First task: clean it. I bought the metal polish used during a previous trip to Germany, after a tip from Lexikaliker on how to clean old brass.

Problem

Unfortunately something went quite wrong. There was a band of oxidisation after I left the sharpener in the metal polish over night. It now looks as if there’s a dent where this band was. Brass is missing in this dent, which is difficult to see on the photos, but quite obvious in reality.

I have two ideas as to what might have caused this.

  1. The brass composition was different where this band /dent is, so the polish could ‘erode’ the material there. This explanation seems unlikely.
  2. I shouldn’t have but the blade and the screw in the same polish. Maybe the metal somehow reacted with the polish which made it ‘corrode’ the brass.

Ok. I got to live with my mistake now, but if I ever get another chance I will keep the blade and screw separate.

Next problem: The blade. It seems slightly too short to cut into the wood. I’ll talk about that another time.

Eisen 402 8

The stationery cupboard, where my colleagues and I get our stationery supplies from, did have pencil sharpeners in the past. I am not sure why there are none left, but I assume it is because most colleagues, especially most support staff, use Paper Mate Non-Stop pencils.

Paper Mate Non-Stop

 

Paper Mate Non-Stop:

The Non-Stop is basically a SharpWriter with tip and eraser in black for the European market, or possibly for all markets outside North America. First released in 1984 the SharpWriter / Non-Stop is a disposable mechanical pencil, made in USA. You can even refill it, if you want. Unlike some other disposable mechanical pencils it is possible to refill leads when you remove the eraser. To advance the lead you twist the tip and – very positive for a cheap pencil – the lead is cushioned which should be good news for users who use more pressure when writing than I do.

Eisen:

But back to the pencil sharpeners… They were all the same type, had a cylinder shaped plastic container and were available in many colours. At the bottom of the plastic container you could see the wording “Made in Germany”. Some of the sharpeners had plain blades without any writing on them, some1 had “Made in Germany” and a lower case e with a crown on top written on the blade. After looking at different manufacturers’ web sites I found that this sharpener is Model 402 from Eisen2, a company manufacturing pencil sharpeners since 1921. Like nearly all other German manufacturers in the pencil and sharpener industry (e.g.  Faber-Castell, Staedtler, Schwan Stabilo, Lyra, KUM or Möbius+Ruppert) Eisen is from Franconia, an area slightly smaller than Massachusetts. Other information and figures I found about Eisen is sometimes contradicting, but apparently they have 60 employees in their Franconian factory and produce 200 million steel blades annually. In 2003 Eisen established its own factory in Taicang3 near Shanghai, and production of the cheaper sharpeners was moved there while the production of more expensive sharpeners for cosmetic pencils is still taking place in the original factory in Baiersdorf. The factory in Baiersdorf is managed by Christian Eisen and the factory in Taicang by Stephan Eisen, both descendants of Christian Eisen, the founder of Eisen Metallwarenfabrik. Altogether, there are 150 employees in both factories, producing 60 – 80 million sharpeners annually.

Lyra, recently acquired by the FILA group, just started distributing Eisen sharpeners in the German-speaking countries, but I am not sure about the distribution of Eisen sharpeners in the rest of the world. They were available in the UK, probably through Impega4, a supplier of stationery for companies.

Model 402:

What is so special about the Model 402, you might ask. The answer is that it is a fantastic sharpener, somewhere between a traditional sharpener and a long point . Sharpening with the Eisen 402 produces a point as smooth as one produced by Möbius+Ruppert’s grenade or by KUM’s Automatic Long Point 2M. Even sharpening “difficult” pencils, like the Dong-A Fable, is no problem with the 402. When I tried to sharpen the Fable with a hardly used KUM 400-5L the lead broke every single time, with the Eisen 402 I managed to produce a great point first time trying, even though I have been using it irregularly for years and with the same blade.

I noticed that my yellow 402, which has an unmarked blade, is not as smooth as the blue one, which has the Eisen logo and Made in Germany written on the blade. It could be that the unmarked blades are worse, but the yellow 402 was in my office and saw much more use than its blue colleague, so I blame the slightly worse performance of the unmarked blade on the fact that the marked blade had not been used so often.

The Eisen 402 is certainly a great sharpener. It outperforms my KUM Streamline Chrome Canister Sharpener 460S and my KUM Long Point 400-5L. The only shame is that it seems to be difficult to get hold of an Eisen 402.

I would like to thank Kent for the Dong-A Fable pencils used in the comparison of different sharpeners. Kent explained me that Dong-A is one of the oldest pencil manufacturers in Korea and that Fable is a relatively new model from Dong-A.

There is a video, produced for local TV stations, with more information about Eisen at Wirtschaftstreff Bayern. Unfortunately it is only available in German and the exact link is changing every month. The video with information about Eisen is from 23 October 2009.

You can find a review of the Kum Automatic Longpoint Sharpener at pencil talk. Lexikaliker has a review of Möbius+Ruppert’s grenade (Google Translation).
