The diamond knife sharpener that fit in my pen case, and worked on even ceramic blades.
Two high capacity fast USB thumb drives with A and C connectors each - one for operating system, one for data.
Sewing latch hook, tiny.
Cloth measuring tape.
A tiny pair of hingeless scissors I could carry openly in any century's clothing.
Tennis socks, the real kind where the left differs from the right and the ankle is padded.
Lint shaver.
Strings of tiny lights, not dimmable, on a timer.
