The description for Cold Iron in the CRB states that "Weapons made from Cold Iron are deadly to demons and fey alike", and certainly those creatures with the Fey trait in the Bestiary seem to have weakness to it in varying degrees.
My question is, since "Fey-touched" heritage for gnomes actually gives them the Fey trait, do they gain a corresponding weakness to cold iron. Nothing in the description suggests this, but the description of the material mentioned above is pretty sweeping so it's hard to be certain.
