I heard great things about hickory bokken, and when I heard Kingfisher Woodworks made excellent ones, I decided to give them a try.  I have beaten the hell out of this bokken over the past two months (and on three occasions attempted to intentionally break it) and it shows little to no damage.  I will be giving a more thorough review on it soon.  Below is a teaser pic.  The kanji reads “mental power”.  – Mushin!
