Dear sir,I like to show you this vintage Swiss army knife that I found last weekend in the garden of my uncle where he lost it 35 years ago!All that time it was laying in the (mostly) wet Dutch soil, I was searching with my metal detector for WW2 relics and found the knife.Back home a cleaned it and treat it with WD-40 and after two nights I could open the blade and the other side tools, after more oil it was like 35 years ago.There was no any sign of rust or corrosion, or pitting, only on the aluminium grips, I think pretty amazing, that’s real Quality stainless steel I would say!My uncle he was very exiting that he got his knife back and he keep it as a souvenir from the past.
