No crafting recipe for "Iron Nails"

Several of the crafting recipes (Simple tagle under Artificing for example) call for "Iron Nails" however there is no recipe for making "Iron Nails". There are masterworking recipes for Adamant and Titansteel nails, but no recipe for the simple Iron ones (which used to be a weaponsmithing task under the old system). I assume this one was simply forgotten when crafting moved to the new system?
