Bring nail clippers.
You will need them at least every 2 weeks for fingers and toes.
(They cut other things too, if you are in a pinch, but try not to use them for anything else than nails, because they may get damaged and then leave your nails jagged.)
These clippers are ingenious, since they actually COLLECT the nail clippings! So much easier than trying to find those sharp bits that have shot across the room!
And, bonus, they are made in the USA.
