Ways to get it wrong
Confusing 'sapere' and 'conoscere'
Use 'sapere' (to know facts/information) for 'Non lo so', not 'conoscere' (to be acquainted with people/places).
Pronouncing 'lo' like 'low'
The 'o' in 'lo' is short and open, like the 'o' in 'hot'.
A small cultural note
Italians sometimes use a shrug and a 'Boh!' to convey 'I don't know' very casually, but 'Non lo so' is always safe.
