Looks great on the stones Freddy.
I still haven't started repolishing the blade on my Dao:

But I guess there is a good chance that your sword and mine both have laminated blades. I think yours is a cracker mate! Hope my poorly Dao looks as good when I've restored it

Hopefully the experts in Chinese stuff will tell you more soon, but my guess is that its a good old one.
