Re: Hanwei Swords...
Truth be told, there are a good many manufacturers of "Japanese swords", but there are only five registered smithing schools in Japan which still produce authentic shinken (translates literally as "real sword", meaning forged for cutting -anything- and sharpened in the traditional manner).
The smiths are limited to the number of shinken they may produce each year. Of the finest of these, many are immediately bought by wealthy collectors, museums, government officials (to be gifted) or by some of the older families to replace swords stolen during WWII. The finest examples, with the best sharpening, custom gold koshirae, valuable antique or custom forged tsuba, etc, will cost you upwards of $140,000 US.
Usually, those which are of fine make, but unremarkable hamon, maker's name, etc, but still far superior examples to many of the sham nihonto being manufactured in the US and Europe, and not from tamahagane, will run you about $3,000-$4,000 US to start.
I suggest if you're interested that you visit Token Mino (
www.iaito-katana.com), click "Katana Sword", and then choose "Tamahagane Katana Sword" (excuse the engrish). The Tamahagane swords start at $3,900, whereas a carbon steel version of the same is $1000 approx to start.
