Way back when I found a nifty web site describing the advantages/disadvantages of different woods used for making bokken. That was a good five years ago and I'm not having any luck finding it again. Does anybody know what happened to this information, or have any insights? I'm not looking for "we all use japanese/white oak" or "Bujin uses hickory", but a more involved discussion, ie don't use ebony, it is very strong but is prone to shattering under shock load (that's about the only thing I remember from the web site a while ago). Any thoughts out there?
Trying to pull this thread back to the original topic... Perhaps you're referring to Kim Taylor's site. He has an excellent listing of various woods and their respective advantages and disadvantages.
