Uni-ball roller pen
Fine-tip roller pen for handwritten notes and math
A rollerball pen sold in several tip widths. The 0.5mm sits at the fine end, which matters if you write small: equations, Greek letters, margin notes crammed into a ruled page. Cheap, common, and easy to keep a few of in different bags.

Working out an idea on a hike is pen and paper for him: a notebook and a Uni-ball micro 0.5mm roller pen. He reckons a 0.7 starts to bleed, and says the finer tip is what you need for the epsilons and exponents in his computer science work.
