NihontoWatchNihontoWatchNanban tsuba as daisho: The sho still has some visible traces of gold, while the dai seems to have been covered with a silvery metal or lacquer in the past. The silver fukurin was added later, but it matches the daisho very well and is carefully crafted. All four hitsu ana are also set in silver. It’s a nice example of nanban tsuba and also a daisho which makes it more infrequent.
