I've never seen anything like these knives. I'll be purchasing one or two as soon as they aren't sold out and I get some mula!!!! I just wanted to share this site I found with you all if you haven't yet seen these. At the site there is some history on the smith. If these knives are no longer available I'll be trying to make direct contact with Hattori.
