One of the presents I got for the kids was a set of youth bokken (29" wooden swords styled after the regular 40-something inch tachi). They came in the mail today, and although the cheap plastic tsuba do not fit exceptionally well, I would highly recommend the red oak bokkens from karatedepot.com as good quality, highly affordable (<$10), and well-made with easy ordering and good shipping speed.
This afternoon Whit and I went and shot some coke cans with the new BB gun. I was shooting from standing and from seated cross-legged today. Whit was doing the watching and gun-carrying as he learns about gun safety. Afterwards we practiced drawing the bokken and stepping forward with a menuchi (downward head cut). I showed him how to rep the men cut in suburi fashion (synching the up and down of the sword with the up and down of the body as he steps forward and backward). It was fun and cool for him but we didn't overdo it because I don't want to wear out his almost-six-year-old attention and desire.
