Re: chisa katana vs kokatana
Wow. That's pretty interesting. To be honest, I don't know what our dojo's standards are when determining correct blade length and how we refer to the varying sizes. The dojo also actually just loaned me a Yagyu-style (I believe it's Yagyu) bokken and the difference between it and my other bokken is pretty significant.
I'll need to ask Nate (my sensei). I've been pretty sick for the past couple of weeks so I've been out of commission since I've come to this question and haven't found the opportunity to ask.
Thanks, Christian. : )
