I really want to love this pencil. I carry this and a TWSBI Vac700 fountain pen.
My main reason for carrying a pencil at all is for occasions when I might need
to erase something I have written, otherwise I use the fountain pen. The problem
is that anytime you use the eraser you end up inadvertently advancing the lead.
You have to be very conscious of the amount of force you are placing on the
eraser to prevent this, sometimes resulting in poor erasing. I have literally
had a centimeter or two of lead sticking out in some circumstances after looking
at the lead after erasing something.
The lead is advanced by a sleeve that is pushed when the lead gets low enough.
However it is also advanced anytime extend or retract the tip. So if you find
yourself clicking the back of the pencil to extend the tip only to write a line
or two, you will essentially advanced the lead three times, once for the initial
extension of the tip, once for the retraction, and a final time for the next
time you advance the tip to write.
Between the eraser issues and the lead advancement on clicking the back of the
pen, I find myself snapping off a lot of lead, which can get expensive if you
use good lead.
All that said I still love the way this pencil feels in my hand. It has a great
weight to it, is well balanced, and has a fantastic grip on it. Based on the
inevitable lead breakage, I have to dock it a point thought and give it a 4/5.
If there is ever a pencil that has this build quality, with tip advancement like
this minus the lead advancement issue, and with the kuru-toga engine, I'll give
it a try instead. Until then I guess I'll just keep dropping more money on
