The 1st generation Kaneie is one of the Momoyama Sansaku, the great three Momoyama masters. Research about Kaneie Tsuba is still ongoing, but there are at least four generations carrying the typical style, iron Tsuba often with Tsuchime ground and inlays in silver, brass and copper. Like Nobuie Tsuba, Kaneie works exhibit a beautifully forged iron.
