Hai Manolo,
the lime juice, how far can it help identifying the sword. how will it look after I pour the lime juice to its edge? is the iron getting whiter or more contrast between the edge and the upper part? the sword once badly rust , then some one clean the rust using autosol / metal polish....so it made the sword dull...the edge line is still straight in its line and the geometry is difinitely perfect.
