Cool a fellow collector. I have no Kattanas yet but I'm planning to get one from Japan which the swords are handmade:). I found a site that order them for a hefty price. About 1,000+ bucks but to me its worth it. The site's url is www.thesteelsource.com
Be warned though, after you view this site, you'll be like this...
They got good deals on fanasty knives and swords too. They even got samuria armor suits too.
