KUM 400-1K

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.

Conclusion:

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.

A brief history of the pencil

There is a very informative PDF about the history of the pencil on Faber-Castell’s web site. Many of the facts are common knowledge among pencil enthusiasts and with only twelve pages you obviously cannot compare this PDF to something as comprehensive as Petroski’s book, but reading this document would certainly be time well spent if you have a few minutes to spare.

Deli pencil sharpener 0635

If you ever go to Shanghai you should visit FuZhou Road. This road is famous for its book stores (including the Shanghai Foreign Language Bookstore), but you will also find many stationery shops there. After seeing the sheer number of different stationery shops, focussing mainly on calenders, note books, diaries, tools used for Chinese calligraphy (like brushes, paper, inkstones) and stationery, you might be disappointed when you actually want to buy stationery: the choice is smaller than expected because many of the shops sell exactly the same items. Other places in Shanghai that sell stationery are big supermarkets (Carrefour, E-mart) or small stationery shops you can normally find near universities.

Keyroad, a relatively new shop on FuZhou Road, is offering items quite different to those offered in the more old-fashioned stationery shops nearby. Targeting Japanophile students, only about half of the space is used for stationery, the other half is used for things like mugs, gloves, toys, etc. Most of these other items are for girls, quite expensive, cute and conjure up associations with Japan, Korea or Taiwan.

There is even a prism sharpener for oil and wax based pencils

The selection of sharpeners was not overwhelming, with the focus on cute looking sharpeners, but to my delight I found a rotary sharpener for only ¥ 25 (£ 2.40, € 2.70, $ 3.70). It is model 0635 from Deli, a stationery manufacturer established in 1988 and employing more than 2000 staff. The sharpener has one burr cylinder and even includes a spring-driven holder for the pencil. There is no desk clamp and no regulator for sharpness or point, but I do not think anybody would mind at this price.

The waste container even includes a prism sharpener in case you need to sharpen oil or wax based pencils as they are not suitable for rotary sharpeners. The manual of the sharpener is in Chinese and English, but the English is rather poor and difficult to understand.

The 0635 has one burr cylinder

Performance:

Performance-wise the Deli 0635 is excellent. The point is very long, even longer than one from a KUM Automatic Long Point. This is a problem for pencils with very soft graphite leads, for colour pencils or for pencil users who use a lot of pressure when writing or drawing, as the point might brake easily. I have not yet had any problems with the point of graphite leads braking, but I stopped using the Deli 0635 with colour pencils. Even the ones with harder leads, like the Mitsubishi Vermilion and Prussian Blue will brake easily when writing if you are not very careful.

Conclusion:

This is an excellent sharpener at such a low price. As it is a cylindrical cutter it should last quite a while without getting blunt. More expensive sharpeners have a desk clamp and let you adjust whether you want a long or short point, but if you like a sharp point and do not want to clamp your sharpener (I assume most people don’t) the Deli 0635 offers fantastic value for money.

Pelikan M320 Ruby Red

Something unrelated to pencils for a change:

Pelikan released the M320 Ruby Red, just in time for Valentine’s day. There is not a lot of information available about this fountain pen yet, but apparently it comes in a heart-shaped box.  There is also the K320, a ballpoint pen version available, but unfortunately no D320, i.e. no pencil version.The Souverän 320 series is the series containing Pelikan’s smallest pens.

You can find more information about the M320 Ruby Red in Englisch at nibs.com and in German at ZC77.
