This is the height of pedantry (and I apologize), but guitar/banjo/mandolin players are not really "opposite" to violinists--they all need to keep the fingernails of their fingerboard hands short. The difference is that the former may choose to keep the nails of their picking fingers long, whereas the fingernail length of a violinists' bow hand is almost inconsequential.
