Authentic Japanese Katana Sword T10 Folded Clay Tempered Steel Real Hamon TK-JP-KT19135 . I am very pleased with the quality of this sword. Everything fits nice and tight, there is no blade rattle once in saya. The Tsuba (Guard) and Kashira (pommel) show no casting imperfections. The Tsuka ito (Cord Warp) is the best I have felt. All parts are of quality. Although I haven't used it Tameshigiri (test cutting), I expect the blade to perform well. Small negatives - first, be in no hurry to receive the sword...3.5 weeks for me. Second, the list of "Do not ...." with this sword seems excessive and sometimes humorous.
