In some discussions we come to this premise:
The number of restrictions for the sword collector and dealer will rise. So the future trends will see less
nihonto collectors/dealers and more tosogu guys.
Shipping a tsuba one dealer said, is put it in your poket, and check in the plane. No problems...
Secondly " it is said, Nihonto from Koto to Shinshinto is a loosing game ". Trend coming soon is the gendaito and later sword, opinions...
Best Regards
