How old is this doorknob? I contact nostalgic as I have their products in my house. They insisted the new knobs do NOT contain any lead. But I don’t know if I trust them (especially since their website said they do)
This is relatively new. Whenever the post was published (within a year of that).

I have these door knobs in my old house but they’re in copper, have you tested those by chance? I tested them with a 3M lead swab and they came back clean but I’m very nervous.
How can lead be transferred to hands from this door knob under normal conditions? Can lead dust come out of it? Thanks!
