The first generation Kaibu Ujiyoshi was making sword from early Muromachi period
however later on there were much mass produce items made.
They made products that is close to Nata rather than Nihonto.
Most of them were called Katakiriba style which is rather strong looking.
The signature was mostly engraved on the blade so it is rare to see signature on the tang.
Those katanas were popular to the pirates of the Seto Inland seas.
The jigane is well grained and is slightly rough texture. The wakizashi was focused
on the sharpness so there is only few made.
The cherry tree inner bark was used to make the saya and tsuka at the time.
There is a municipal Kaiyo Museum in Kaibu city,Tokushima Prefecture
