That is a very nice example Katana! congratulations!
The hilt is extraordinary! Are you sure that it is not overcleaned silver? It does not look like silver, but such a nice workmanship would deserve it to be silver.
Kaskaras are becoming more and more popular over the years. Once there was a lot of them for sale on ebay, but nowadays it is quite hard to buy one, certaily impossible to buy a nice one.
In my collection i have just one kaskara, nothing in comparison to yours, and I've opened a new thread to show it. A new thread, because your sword simply deserves a separate thread.
WELL DONE!
