Question about Ironguard spell (Spell Compendium)

[Hierophantasm]

Hey guys,
Just wondering if anyone has looked at the spell "Ironguard" (p. 125) in the Spell Compendium. In particular, I was looking for some advice as to whether the spell, which reads, "metal items (including metal weapons) simply pass through you," would apply to all types of "metal" weapons, such as cold iron or silver, or if it just applies to non-typed weapons, such as regular or masterwork longswords.

I would say yes, all metal weapons (assuming metal weapons are iron or steel, that would leave the spell fairly flacid when dealing with "metal items" - a great deal of metal items are not iron or steel.

But that does not include special materials that aren't metal, such as darkwood or stone armor.
