I don't believe knowledge skills can be used untrained. Personally I don't really agree with this stance. For example, why do I need Knowledge Nature to know what a Blue Jay or a sparrow looks like? In my game I usually allow players to attempt a knowledge check for a DC or 10 or lower or 5 for Knowledge skills like Planes or Arcane because information in those skills aren't really skills that come up in daily conversation for most medieval people unless maybe you're playing a Puritan campaign.
