Bront, Ekilu's item: [sblock]Your shield, Spirit's Shell, was further enhanced by a water genasi priest in Taala's service. Now the sturdy little clam can open up and bite arrows and other projectiles, snapping them out of the air before they can even hit you. Mechanically the shield is now a +3 arrow deflecting sheild. About once a month, the shell opens of its own violition, revealing an arrow seemingly made of mother of pearl. You find it to be particularly effective against monsters of the spirit type.[/sblock]
Seriously, though, assuming you are parodying Kel's "my sheet may not say it but I'm actually an expert in this" position, I do see your point, but I can also see the other side--for instance, Nissa is a fey, so even though she doesn't have Knowledge (Nature), I imagined her having information about fey (and elementals like her mother) in her Knowledge (Nobility) and Knowledge (Local) skill categories, and she probably wouldn't know as much about humanoid nobles or locals. However, according to a strict reading of the knowledge skill descriptions, she wouldn't even know what a nereid is (even though she is one). In that sense, trying to nebulously decide on knowledge based on concept and the character's nature, while a slippery slope (which your example represents perfectly I think), seems a worthy cause.
