Very lightweight, the main feature I was interested in is its ability to use up
nearly all of the pencil lead. It doesn't quite have that ability without a
trade off, because when the stub gets down to 15mm, it no longer grips the lead,
and allows it to spin freely inside the sleeve.
What that means is you'll no longer be able to write with a sharp point, because
the lead will always rotate to the bluntest orientation, effectively writing
with an ellipse. If you have an unusual grip where you hold the pencil
straight up and down, you'll be able to write with a 0.5mm diameter line, where
the rotation of the lead isn't a factor.
If you're interested in ultimate conservation, you might put up with the lead
rotation, but most people will just choose to eject the last 15mm and go on to
the next full stick.
The sleeve retracts as you write, so it can write a fairly long time between
advancement clicks, but the sleeve drags on the paper if there's insufficient
stickout of the lead.
The interesting feature is that the point is spring loaded, so you can push the
sleeve back manually on the paper by pushing down on the tip slightly. The
sleeve will retract and the lead will be exposed enough to write unencumbered.
The pencil disassembles easily and fully, in case you get a fragment jammed in
the mechanism, so it's a simple process to clear out.
The lead reservoir is pretty narrow, basically the same diameter as an ink pen
refill tube, so it won't hold as many as most other pencils.
Unscrew the top from the barrel, and the eraser holder remains with the
reservoir tube; pull it off from the tube and the leads can then be refilled.
The tip has to be manually pushed in for pocket storage, not as slick as the
Pentel GraphGear 1000, but at least it does retract fully unlike the fixed
sleeve types. It's light enough that no damage should result from accidental
The clip is nicely done, with a spring loaded hinge that allows it to clip
securely onto very thick objects without having to use your fingers to spread it
open; just press on the rear of the clip and it opens up easily to clip on your
shirt or notebook.
Bargain price, well worth the price of admission.
