Nice collection. Except for the "Katana"
I wouldnt consider it a Katana. Its an insult to the term "Katana"
1. The tsuba appears to be a part of the blade.
2. It does not appear to be forge-folded, as it does not posess a hamon.
3. Its not curved enough
4. Its ugly =/
See real katana:
Sorry, I'm somewhat of a japanese sword enthusiast =p Nice knife collection though.
