Today I want to show you KUM’s Correc-Combi, a sharpener in an eraser case, which I bought this April for €2.79 (~$3.65; £2.25) in Müller in Volkach, Germany.

The eraser
The blade of the sharpener is fixed to a plastic body which in turn is encase by (quite a large) eraser. I am sure it will take quite a long time to use this eraser up.

The sharpener
The performance of the sharpener is quite good, certainly much better than the performance of KUM’s 400-1K. The sharpener produces thin shavings with an average thickness of 0.2 mm [1]I recently bought a calliper in Lidl, so I thought the thickness of the shavings would be a good thing to measure, especially since Lexikaliker mentions the thickness of shavings in his blog..

I also saw a set square from Globus by KUM for 49c (~ 65¢; 40p) in the same shop and couldn’t resist buying it. You might remember the list of sharpening angles of the different sharpeners in the KUM 400-1K blog post. When I figured these angles out, two years ago, I didn’t have a set square – so this time figuring the angle out was much easier. With about 22° the sharpening angle of the KUM Correc-Combi is very similar to the sharpening angle of Möbius+Ruppert’s grenade.

Conclusion
A very good sharpener/eraser combination. The lid fits well, despite being a ‘click in’ lid (no screw thread) . The performance of the eraser is similar to that of KUM’s Correc Stick. It could be better, but is by no means bad. The performance of the sharpener is quite good and overall this eraser/sharpener combo offers very good value for money.

I would like to thank Hen Chung from RAH for the Staedtler norica 132 46 HB you can see on the photos. It’s the less purple version with blind stamped “SRP” [2]My more purple version is blind stamped “SRL”..
I found this KUM sharpener on a recent trip to Manchester. Unfortunately the model number is neither printed on the package nor on the sharpener, but it is probably 400-1K. Paperchase in the Trafford Centre sells these wedge-shaped magnesium-alloy sharpeners for £ 0.75 (~ € 0.82, $ 1.12). This does sound quite cheap for a sharpener that can potentially be used for a long time, but for just a few pence more you can get the 400-1E from Cultpens, a similar magnesium sharpener that comes with two spare blades, while the 400-1K does not come with any spare blades.
KUM has a very good reputation. Like most German manufacturers in the pencil and sharpener industry they are from Franconia (more details can be found in the Eisen 402 article). Because of KUM’s reputation my expectations were quite high and I was soon disappointed when I realised that I got another sharpener from this company that does not perform as well as expected. Previous disappointments include the KUM Streamline Chrome Canister Sharpener 460S and the KUM Long Point 400-5L. My only good KUM experience with a sharpener so far is with the Kum Automatic Longpoint Sharpener, reviewed at pencil talk.
To sum my problems with the 400-1K up: it does not sharpen the pencils well. The sharpener will produce a long, continuous sliver of shavings, so the blade of the 400-1K is not blunt, but the graphite will end up with gouges or spirals. Good sharpener like the Möbius+Ruppert’s grenade, reviewed at Lexikaliker (Google translation), or the Eisen 402 do not have this problem.
The point produced by the KUM 400-1K is rather short and blunt. The sharpening angle is only about 24°. Normally you will only get a shorter point if you use a sharpener for coloured leads. The 400-1K‘s point is certainly shorter than the one produced by Möbius+Ruppert’s grenade.
It is nice to have a sharpener that produces a shorter point, but I am not very enthusiastic about the KUM 400-1K. Maybe I got a “bad one”. It does perform similar to other average sharpeners, but you do not have to spend much more to get a good sharpener that will certainly outperform the 400-1K.
I would like to thank Kent for the Staedtler 134 yellow pencils used to compare the different sharpeners.
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:
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.
The Eisen Model 402 in blue and yellow
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, some [1]I assume the older ones 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 Eisen[2]pronounced like iron with an s sound between the two syllables, 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 Taicang [3]Taicang is very popluar with companies from America, Europe, Taiwan and Japan. About 100 German SMEs settled there. 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 Impega [4]Impega became Lyreco in 2009, a supplier of stationery for companies.
Dong-A Fable, sharpened with (left - right) M+R grenade, Eisen 402, KUM Automatic Long Point
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.
Eisen 402 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.
