For a long time I am looking for more information regarding this bokken (link below), but it seems that no one who has seen this bokken, or have some more photo.
I even sent two e-mails to the respected Stan Pranin from Aikido Journal, but there is no answer from him
I would be very grateful if anyone of you knows something more,
however, the first replica I made according to this picture, but I would like to know more detail, so that next be even better, and more accurate measures of the original bokken,
bokken is specific by one detail, which for me as a bokken maker quite intriguing.
