That's not really a supid question
EDIT:
This all depends who you're facing, and I mean the person themselves. You should use it to slice up their *****. This would help keep distance between you and your opponent and you could open yourself up to new or similiar combos. but when it comes to throwing it could be a different story.
If you know they're gonna catch it, then just throw it away. Trust me, it's NOT worth it. Better in no one's hands then in your oppnents, so don't throw it to pros. It's reccommanded that you just use it to strike them then throw it. Leave the throwing to true projectiles (like turnips, saturns, and bombs)
This all really depends on your current situation in the game
