In the area of Chinese fakes and who can you trust? We acquired this sword personally from well-known author Anthony Allen. of "Allen's Authentication of Ancient Chinese Bronzes"

Height 1.13", Width 2",Length 21.5"

Notice some cloth remnants in closeup of the hilt?

That is an amazing bronze, and I am glad to know its provenance, because I assume every one I see is a modern fake. The patina is a wonderful blue green, and does indeed seem to have fabric incorporated into it. Could it have been a metallic thread, or do you think it is more like a fossil where the organic component has been replaced with metal oxides?

It is also nice to see the edge with a slight color difference. It seems that these were quite sophisticated with a harder bronze at the edge and softer shock absorbing bronze in the body. This technology was the conceptual foundation for harder steel edges on Chinese swords beginning in the Han. Basically it seems that as soon as the Chinese had iron, they went to massed produced folded steel with differential hardening almost instantly. The sophistication of these bronze blades provided the conceptual framework to make that possible. In their time they were second to none.

It is also interesting to note how simple and ergonomic the design is. Bronze guo and cong from the period are highly decorated.

A very nice example with excellent provenance. The presence of the remains of fabric wrapping would lend itself to carbon dating if it is not totally fossilised. I am not sure it is necessary in this case but would be a certain way to prove authenticity which cannot usually be done with bronzes.
