Over the past 15 years or so, I have saved certain articles, or bits of information I found interesting, along the way. Perhaps there is something in there that will be helpful for others? I have credited the original source(s), where known.
Of all of the info I have saved through the years, this is the most referenced for me. It is a compilation of numerous posts, from various makers, in a couple of different forums. For shakuhachi makers, I feel there is some valuable info here. As I remember, Ken, Toby and Perry were the major contributors, though there might be comments from others, as well.
