Reddit mentions of Staedtler Mechanical Pencil, 0.5mm (925 05)

In the "IDGAF, so long as it doesn't break" category?

I really like the Zebra M-301. Super classy steel bodies, and at least where I am, they're frequently on sale/clearance. I picked up like 3 2-packs for something like 1.50 each. I figure that'll probably last me the next decade or so, most decent mech pencils don't easily break.

For a bit more, but still under 10 bucks a pencil, I have a bit of nostalgia for the Staedtler Mars Micro 775. Have a red one my mother bought me in the 8th grade (so...2001 ish), and it still perfectly works. This one is also pretty widely available, or in a three sided variety, see this one.

And in Pentel flavours, eh, GraphGear 500. If I lose it, well, my family works on a university campus, the bookstore there carries ten gajillion more. The 1000 is a nice upgrade, along with the .03 Graphlet (which I used in Japanese class a lot for Kanji).

Thanks for detailed response I really appreciate it. Seems like it's between the staedtler 925 and the Graph Gear 1000 with the Roulette Grip. There seems to be a couple versions of the Staedtler with the 925 25-05 and 925 35-05 being twice the price of the one I linked. Is there difference substantial and I hate to bother you again but of the ones I linked which one would you think is best for long writing for a long time? Thanks again for all the help.
