Platinum Pro Use 171

It is not rough like a GraphGear 500. It is more like a Platinum Pro Use 171. Despite being a heavy pencil, it balances well and the center of gravity is about half an inch above the grip.

The design and construction of the regular Pro-Use is virtually identical to the Staedtler 925-25 series, differing only in some aesthetic ways like the grip and tip. The Pro-Use 171 is neat too - adjustable sleeve length, lead suspension mechanism that can be toggled on and off. Edit:. I should add they've been making pens since 1919, so they are a well established brand in the industry.
