they do all the time...
but if you're talking about fights between people with superpowers that cause 10kilometer craters in the earth then ya... a single throwing knife isnt gonna win it for ya.
and that fight between sasuke and itachi was awesome, especially that scene demonstrating how awesome they both were with shuriken, constantly bouncing them off each other at super speeds. the irony of this whole thread, is, that if you keep watching the fight, sasue actually hits itachi with a special oversized shuriken that exploded right after itachi dodged it.
