NBTHK certification of 1968: "Kicho". Condition is relatively poor: rust, missing inlay, scratches.
While representation of the snowflake is rather standard, the meaning of the other cut-out design was initially less clear. Similar symbol was found at (1) "Kokusai Tosogu Kai, International Convention & Exhibition, September 24-25, 2005, The Frazier Historical Arms Museum, Louisville, Kentucky, USA"; on page 21 there is a photograph J-6 of a ko-tosho tsuba with "iris theme openwork"; (2) Japanese Swords and Tsuba from the Professor A. Z. Freeman and the Phyllis Sharpe Memorial collections. Sotheby's, London, Thursday 10 April 1997; page 11, lot 6 - a ko-katchushi tsuba of early Muromachi period fith "simple design of stylized iris". In both sources the symbol is explained as 'iris" (kakitsubata).![](http://varshavskycollection.com/wp-content/uploads/2017/10/iris-384x400.jpeg)
