Are you sure it is black oxide and not black nickel? I have many customers that run pen clips , and all are heavy bright nickel deposit... It wouldn't be a far jump for a company to plate black nickel on these..... hope this helps ,

Dear Mr.Dupuis,

Mr.Landrette is right,one solution for your pen clips is a "black nickel plating" over bright nickel, obtained from nickel baths with additions of zinc and sulfur.But the grey-black deposits obtained in this way do not resist to corrosion and rubbing and must be lacquered with a clear solvent lacquer. Another and better solution is to apply, over bright nickel, a tin-nickel "gray-anthracite" alloy which is very decorative and corrosion and wear resistant.
