Or shuriken are a volley and are then useful only for poisons, which are too expensive at for one dose, and now you need three doses per attack or you've wasted a feat. That's why I didn't use that. Well, that and I wanted to do something original.
Wouldn't Sneak Attack apply only once to an attack? Those three shuriken would only use a single attack roll, be aimed at only a single target and also have SA dice added once, not more.

Basically, their big use would shine in applying poison to a target, as said before. Plus, you could just rule that for applying poisons to shuriken, they also count as ammunition.
