Sharpening a Wopex 11

You might have already noticed that the Wopex is one of my favourite pencils. It is the pencil I use most often when writing on paper where ghosting/graphite transfer might be a problem. There is however one problem that makes using a Wopex an experience less exciting than it could be: sharpening this pencil.

Wopex, presharpened

Desktop sharpeners are not good at sharpening pencils with such a hard casing. They won’t stop automatically, too, which means that you might shorten the pencil too much when using a desktop sharpener and you’ll got a less than exciting finish where the blade cylinder stopped.

A normal prism sharpener does a better job when it comes to sharpening a Wopex, but the lead tends to look rather porous after sharpening and the fine point created will break much easier on a Wopex than on a pencil with a traditional lead.The special Wopex sharpeners don’t seem to do a better job than any other prism sharpeners. At least they don’t do for me, maybe I don’t use them the way they should be used. One example is shown here, but the point doesn’t always look that bad. A better looking point, made using a prism sharpener, has been shown in a previous blog post.

Wopex, knife sharpened

The presharpened Wopexes1 are looking and performing best. They are sharpened on an abrasive surface, something that is not necessarily practical for home use because of the time and dust involved. Searching for an alternative, better than a normal prism sharpener, I thought of using a knife to achieve a point similar to the one of presharpened Wopexes.

Unlike most other sharpening techniques, in which blades engage the pencil’s wood (and later, graphite) at an angle more or less parallel to the shaft, the pocketknife’s blade is applied perpendicular to the pencil’s shaft.” (Rees 2012, p.46)2

There is a special pencil knife for sharpening and erasing, but I used a normal knife. In this case one with a high carbon steel blade, but stainless steel blades work just as well. The results are good, better than what I get from a prism sharpener, including the Wopex sharpener, but are slightly worse when compared to a presharpened Wopex.
