I'd originally intended to purchase the Staedtler 925 85, the Regulator. I've
used Staedtler pens and pencils for years. Generally, I find them to be
reliable, high quality writing/drawing tools.
But, the Pilot S20 drafting pencil was so beautiful, I took a chance and I
ordered it instead. The moment I held the S20, the instant I put the lead to the
page, I knew I'd made a good choice.
The S20 is perfectly balanced and fits my grip like it was specifically made for
my hand/fingers. Weight is just right, neither too heavy or light and the same
for its balance. There are no rattles or unwanted flexing when pressure is
applied; no distracting features whatsoever.
Simply put, the S20 is an elegant pencil that looks every bit as good as in the
advertising photos. It performs beautifully, laying down a smooth application of
lead to paper, almost as if the line is flowing onto the page. While it has yet
to stand the test of time, it has the feel of an instrument that will.
