The standard length of the tsuka of our iaito is 8.5 sun (approx. 24cm/9.44in). Usually, depending on the blade length you choose, our craftsmen will select the appropriate tsuka length in order to keep the best balance possible. However, you can of course still choose the tsuka length you would like. In that case, we won’t be able to guaranty that you will get a perfectly balanced Iaito.
