The Pilot S20 is a very special pencil. It could be classified in many ways – as a drafting pencil, a mechanical pencil, or as a luxury pencil.
The S20 has the shape and features of a drafting pencil, and it is a drafting pencil, but it’s also perfectly usable as a general purpose mechanical pencil. The construction and finish are also at a level where a few small changes would make this pencil quite at home at upscale fountain pen shops, selling for much more.
The distinguishing feature is the wood casing. A rich dark brown, the wood gives the pencil a very pleasing appearance, and makes it very comfortable to hold. The wood imbues the pencil with a pleasant, warm, humane aspect.
The balance and grip are superb, in my view. There is a slight concave dip in the traditional “grip” area. You just want to keep holding and using the pencil.
The cap is marked with the lead diameter, and has a lead grade indicator window on the side. These two features are the ones that, if removed, might cause the pencil to be mistaken for something much more expensive.
The lead advances by clicking the cap. The cap can be removed to access an eraser and the lead chamber.
If you want a drafting style pencil that doesn’t look like it might be a medical instrument, this is a great choice.
