@farmerman,
I've done an immense amount of hand drafting but either used pencils or rapidographs (early on) and later, some new sized pens, preferred rapidographs - but mostly mechanical pencils - which I do very much still like. I bought one terrifc mech pencil I craved for myself and gave it to a relative for a c'mas present. Should have kept it.
Anyway, I also like ink pens. Still have the Mont Blanc I sat on at a conference (long story), in case one day I send it to MB and they'll fix it for me (replace casing the gold parts are still fine; at least they used to fix them). Have a tiny pen of my mother's, circa the 1910's. Eventually tossed my father's Parker, what a leaker, but handsome looking pen. I suppose I should have kept that too. So, no, I don't collect them, but I like them a lot.
