Rare tsuba custom made (thick and stout) for a Tanto dagger. It is referred to as a night and day tsuba as you can reverse it with one side being shiny and reflective for day time use and darker and plain and nom- reflective for more covert use at night time . Quite a novelty and unique piece picked up at Yasakuni shrine antique market in Tokyo a few years ago . In great condition with no flaws , rust , or wear marks . Please contact me if you are interested .
