From Aoi Art : Bicchu Kami Tachibana Yasuhiro is a very dexterous
sword craftman who creates a blade pattern reminiscent of
Katayama Ichimonji from a Doranba Hamon-style work that can be
made. Jigane is made using high-quality Jigane from Osaka jigane.
There is a weak Jitetsu in the middle of the table, but it is not so
noticeable and you can see the pale Utsuri in the work of a decent
bullion and a single letter copy.
