My roommate is allergic to plastic, which gets in the way of her finding a salt grinder, because apparently every salt grinder she and I have found, no matter what the outside is made of, has plastic gears and/or plastic griding bits, which is ridiculous, really. Why make a salt grinder with a grinding part that is weaker than the material you're grinding? Anyway, she can't use those because little bits of plastic get into the ground up salt.
Does anybody else know where to find a salt grinder that has like, a metal grinder? Granted, she's allergic to lots of metals, too, but metal being stronger than salt means it's unlikely to be a problem the way plastic salt grinders are. Any help would be greatly appreciated, as I don't know where to even begin looking.
