Throwing Knife rulings:
2015-06-22: Throwing Knife’s triggered ability triggers before blockers are declared. If you use the ability and destroy the targeted creature with lethal damage, it won’t be on the battlefield to block.
2015-06-22: Throwing Knife is the source of the damage dealt because of its triggered ability. For example, you could sacrifice Throwing Knife to deal 2 damage to a creature with protection from red, even if Throwing Knife is equipped to a red creature.
