Someone is offering me a hand-made katana for 690 USD, but since I am no expert I can not tell if it is a fake or real.
Here are some pictures of the sword: http://foto.volja.net/view-album.php?lang=slo&album_id=7819
According to the seller it was made by Kunisada-sama, Bizen, Japan.
He also said that only hand-made katanas have hammon.
