Back in 1995 when I was an impoverished college student I bought
myself a Koh-I-Noor
. It was fantastically expensive for a pencil, about $10. A crazy impulse purchase for someone who literally
other student's garbage
to save money.
I used that pencil all through college, wrote up 3+ years of math
papers in impossibly tiny, precise handwriting. I'd use one page per
assignment when most students used five or more. And ever thrifty,
always on the back of some discarded printout. They're beautiful old
papers. I was so terribly focussed studying homographies,
complex analysis, and the axioms of logic.
I still have the pencil. It works great.
