While the KUM Masterpiece is a fine piece of engineering and one of the pieces of Pencil Ephemera about which I have been the most excited lately, there is something missing that I hope we can add to the Pencil World. The instructions on KUM’s website are not great. The video is produced to a quality standard that does no justice to all of the research and work that went into this sharpener. I have practiced a bit, and I think I have figured out the best way to use this sharpener.
First, start with a quality pencil. This machine begs for at least a good Semi-Cheap, if not something premium. From there, follow these steps:
1) Use the hole marked 1 to sharpen away the wood. Do this until the graphite hits the auto-stop (the blue piece). You might notice that there is a piece of wood stuck to the long piece of exposed graphite on one side. What you want to do is push the pencil into the hole and gently against the blade again, and keep doing this until you encounter no resistance at all, i.e., there is no more wood being cut.
1A) Another option is to push the blue plastic out of the way before step 1. Then you can expose graphite to your Pencil Heart’s content. You can then proceed on to the shaping the graphite.
2) Use the hole marked 2 to sharpen the graphite. At the beginning, the exposed wood of the pencil will not fit against the cavity of the hole. You’ll have to do your best to center the burgeoning point. Turn the pencil, and watch fine pieces of graphite pile up on top of the sharpener. Here, you have a couple of options:
2A) Bring the graphite to a nice point, and then stop. You will have an odd-looking point that is not as sharp as the Masterpiece is capable of producing. But maybe you don’t want one that’s that sharp. Or maybe you are pressed for time. The advantage of this method is that you can sharpen the graphite again to a point without having the sharpen the wood again. You can skip Step 1 and just point the graphite at least one more time.
2B) Push the point into the second hole until you notice the blade cutting wood as well as graphite. It is this method which will get you the acute point that you see on the pencils at the top of this post, and this is the Insane Point for which this sharpener is made, I believe.
I hope this is helpful and not overly cheeky to KUM. If Comrades find better/alternate ways of using this sharpener, I’m sure we’d all be glad to read about them in the comments section. Also, check out Gunther‘s and Matthias‘s posts about the Masterpiece, with way better photos and more information about this fascinating sharpener.
