"Žofie has few spoons."
Translation:Žofie má málo lžic.
There is a difference in meaning between "Žofie má málo lžic" and "Žofie má několik lžic".
"Žofie má málo lžic" implies that she is nearly running out of spoons or that she has too few spoons for some purpose, while "Žofie má několik lžic" does not have such connotation.
(And no, there is no connection with "The Spoon Theory")
Disclaimer: I am learning, too, so this is a GUESS...
I think that "několik" is (more or less) "several." If Žofie has several knives, the actual number of knives she has may or may be not be important.
With "málo," which is (more or less) "few," there's sort of a suggestion that she may not have enough knives -- say, for the eight people she will be hosting for dinner tomorrow.
So... if, for example, Žofie has six knives, she could have either "několik" or "málo," depending on the context.
