Ink?! When I was in school we wrote on clay tablets with reed styli. We had to maintain the styli with copper knives. Later, even the most reactionary teachers would let us use the new fancy bronze knives.
Heh, kidding aside I have all the writing implements: glass dip pens, metal dip pens, quill, even some home-made experimental pens (the one made from a plastic drinking straw is actually pretty good).
Glass pens are okay and great to clean but of course there's zero flex in the nib so it's not one that I reach for very often.
A calligrapher in the BBC series on the history of writing makes one out of a Coke can. Some day I'll get around to trying that.
