Jim, that would be me in those videos.
I appreciate you referencing them, and I hope others take a look. I know that some may not like what I'm doing, but those videos are more of a personal experiment based off of a personal question... I just post them in case others have the same question.
As for the KWW boken... let's just say it is still the only one standing after these many tests. I am only about 1/3 to 1/2 of the way through my tests. I have a list of bokken I plan on testing, and currently have a Brazilian Ironwood up next, followed by a Wenge bokken and Lignum Vitae bokken that should both be here next week.
I plan on getting one of KWW's enhanced bokken soon, though it feels like it may be overkill! I would be happy to answer others' questions on this and other types of bokken. Frankly, I am eager to hear others' experiences.
I have KWW Grade 7 bokken and jo and they are great - although they feel lightweight, they are extremely strong and hold up very well - I also have a Dymondwood set from Bujin - very heavy and very strong and the KWW hickory holds up very well against the Dymondwood in paired practice - my first choice in training is the KWW though.
