Following the assistance of the forum, I had realized that I need a Bunka :-)

I was happy to receive a positive reply from Sichini which apparently will make me two of them, have been wanting to try a Watanabe for a long time.

I was not able to find any reference to a Watanabe Bunka/K-tip santuko (or the other names this shape has) by Watanabe, does anyone out there have one? could you share a pic and feedback.
