I always take a victorinox classic sd. One of the tiny keyring knives. It has the added bonus of being able to pass through airport security when attached to keys as they never seem to notice it...
Never found that I have needed a bigger knife as I can do everything I need to with this one, chop veg, slice cheese etc.
maintenance is use it till it falls apart or I lose it, then buy a new one.
