Solid all-metal body & most parts (one exception, for good reason) are metal -
either anodized aluminum or highly polished brass. Clean lines, clean threading.
Smooth & solid click feed advance mechanism. The clip might look like a piece of
cheap tin in the photos, but it is thick & strong. The knurling on the grip and
extension knob is more squarish (less of a diamond) but still good for grip
One great thing about this versus other retractables (like the Pentel Graphgear
1000 or the Ohto Super Promeca) is that it retracts far enough to allow room for
a reasonable amount of lead to remain extended from the guide, but be protected
inside the body. The result is not having to constantly fuss with retracting
lead before retracting the guide, then re-feeding lead after extending the guide
again. Very useful overall.
My only gripe : I wish it was available in 0.7mm (my favored lead size!).
Very light marking, pretty good strength (although I'm used to a 0.7mm for most
applications, so it takes some getting used to using a lighter touch to avoid
breaking lead/drilling through the paper/poking through my fingertips . . .)
