Right Brian, said the same as you, but he wants to tell no prices. So he is the boss. When someone is interested in the Ko-Ichimonji, I think he will sell for a really good price.
Secondly there are some more very good swords, he don't list, cause he won't sell them the other day. But will sell them today. So if someone wants to buy a treasure ( not in Japan..!) in Germany, talk to him.
