I have used KUM’s Automatic Long Point sharpener, a two-step sharpener, for six years now, but I can’t say that I’ve ever been very happy with it. In the end, it didn’t use it much at all – saying that: it is a good sharpener for Staedtler’s Wopex, though.
After reading Lexikaliker’s blog post about the KUM Masterpiece, a very similar sharpener with a magnesium body, I couldn’t resist and had to try it. I’ll spare you most details about the sharpener as I’d never be able to write them up as well as Lexikaliker anyway.
The Masterpiece is quite expensive. I paid €9.25. Luckily Lexikaliker was kind enough to help me get my hands on one. No wonder it’s expensive: There is a lot of manual work involved and that doesn’t come cheap in Germany (but in this case it’s much cheaper that products from another German company involving a lot of manual work).
It’s a two-step sharpener, meaning that in the first step you only ‘sharpen’ the wood away. You then move to the second part of the sharpener where you sharpen the actual lead of the pencil.
The Masterpiece comes in a plastic container that is in a neoprene case.
Actually, the first time I used it I damaged the lid of the plastic container that sits inside the neoprene case – closing the snap fastener needs so much force that the case under it got a crack.
I can’t say that I get much better results with the masterpiece – compared to KUM’s Automatic Long Point sharpener, but it was slightly easier to achieve good results. Another benefit of this model: You can also slide the blue plastic stop off to expose the lead even further before sharpening in the second step. One last point to mention: The Masterpiece has an even more acute angle. Technically the angle for wood and graphite are different. In reality, assuming you used the built-in stop to expose just the right length of graphite, you get an angle of just over 15°. This is the most acute angle I know.
It’s a nice sharpener, top marks for beautiful shavings, and I’m sure it will see more use than it’s Long Point sibling, but I still prefer my Deli 0635.
