Is it common for another alloy such as copper or gold to be used in the core of a blade ? Look closely at the pic ,I soaked about 6 inches of the tip of my blade in vinegar just to see what the result would be and it appears there is a whole other sword inside of this blade made of a mixed alloy with copper and the dot now looks gold. When I gently rub the blade down with lime juice or vinegar the sharp edges darken very quickly but the center does not .Soaking the end of the blade revealed what appears to be mixed cooper gold and silver or nickle down the center
