For processing:
The pencil is not entirely of aluminum as the Pentel Graphgear 1000 but has a plastic body and a grip / tip made of black anodized aluminum.
This makes it lighter than many other signs pencils, but that's what makes it ideal for working longer.
The pen is perfectly balanced, so that the tip tilts forward when poised easy to Sift the finger.
The lead guide is pretty long, which so far is not yet mine stopped and one can well see to your own workspace.
The mechanism is as far as I know from solid brass and is working still, absolutely precise and reliable.
All in all, I pencil Recommend unreservedly and would buy it again at any time.
