It’s just amazing, I’ve never seen anything like this!
It is impossible to believe, but this is a rapier.
It was manufactured in the mid-19th century by the technology of the old masters as a gift to one high-ranking person.
Such exceptionally flexible rapiers were made in Toledo in the 16th beginning of 17th century.
In the gun shops, they were sold necessarily coiled in a circle to show its flexible properties.
