Dear Christina.
Thanks indeed for seeing my URL http://nihon-to.blogspot.com/ altough it wroten in bahasa Indonesia. This blog being wrote because of a lot of monkey bussines in a kind of what so called belt Japanese sword. It's seem like not a real Japanese sword like Katana's.

But if you are interesting for having this such one, may I suggest you to take a look for any Japanese Culture information services. So there you may get such authoritative sources.
You may come into a nearly Japanese Culture as well for such sufficient direction.
