Hello all, I've searched for my ideal mechanical pencil on-and-off for years now, and finally came to my senses to stop and "ask for directions". I'm in a physics PhD program, and spend some serious time with a pencil in hand. That's been the case for years, though, and I'm more than ready to plunk down some cash on one that'll last me - and more importantly, that'll be comfortable for the duration. What I'm looking for: - 0.5 mm graphite - Aluminum/stainless steel/metal body, circular (solid construction) - No clip I understand that "no clip" is an odd requirement (and the one that's causing me trouble in finding a suitable model), but I suppose I have odd hands; anything with a clip winds up irritating my hand in the end. It's not the end of the world, and I've obviously dealt with it over the years, but finding a good pencil without a clip would just make the heck out of my day. Dave's has yielded some decent results, but not exactly what I'm looking for. Models I like anyway are: Staedtler 925 25 Pentel Graph Gear 1000 Can anyone help me out? Thanks in advance!
