Earlier quoted context omitted.
Since you're into pencils, have you tried the Pentel GraphGear? Or, my personal favorite, the Rotring 800?
I don't like pencils, for my vision the color is too low contrast with the paper compared to black ink, or even blue ink, and for that reason I prefer a .7 nib to a .5, the thin lines also result in less contrast (they also make a scraping "sound/sensation" on the paper). but I didn't comment just to say that, but I selected your comment as a representative sample for a broader comment: hey everybody, could you tell…
Basically, I like it because it's a high quality writing utensil that I won't get worried about.
A lot of people don't like the 800 because of the retractable tip, but as someone who has this pencil in their backpack all the time (and who has had the non-retractable version unfortunately ruined in a backpack) it is an absolute necessity.
