Ok, I have become the HUGEST fan of KILL BILL ever since I laid eyes on those WONDERFUL movies, and I was wondering where the best place to obtain a real working (tempered, full tang) sword would be. (For fun, I'm not going to hack up people with it). I also know that Hattori Hanzo is not a real person (he's a charachter from an old kung fu series). In any case, if there are any GOOD replicas of the movie swords available, I would also like to know where those are, if anyone has any information. Thanx!

You can find "real" Katana's and Shinken on the internet. One site is here http://www.jidai.jp/Shinken.html
Be prepared to wait several months for it to be constructed to your specifications and be willing to pay a lot of money for it. They start around ten thousand dollars and quickly work their way up from there.

If I were serious, I would commision a sword from a Japanese swordsmith. This can be done within reasonable cost limits.
The sword you would get, would retain its value and increase over the years. I would look at spending (Ok, gonna convert to $$) $3000. On a hand made blade and hilt. I would also insist that it is signed and dated.
Refrain from any decoration other than the swordsmiths name and date. There is a good reason why!
I currently own 6 japanese folded steel knives of various styles. They are all my loved ones. The cheapest being $170.00 going onto my prize piece, now valued at $890.00.
I use my $170.00 blade when I'm hunting. It is a natural skinner and boner and does the job 100%. It is my fave as I use it so much. We have been through a lot together

10K is a tourist price. For 10K I would expect a hardness of AUS-10+ on the blade and a hilt with gold thread and ornamentation. And it would have to be made by a NAME. an individual artist, not a company. It would also have to be balanced to my size and weight.

Nerds!

I'm gunna make you juggle my 3 most loved knives FD.
You don't wanna drop 'em!
