The Foam bokken.
The reason I have the foam bokken on me during the day time, first off; you are not allowed to carry any weapons outdoors full stop.
I do not advocate the breaking of any laws, but who to say what I carry as a Ninja of the night? Use common sense and please study the website carefully it will answer some questions ok.
“Think about it” You can't do filming for the BBC walking around with a real Ninja sword, please consider there is a lot they can't show or talk about on TV.
Also consider this, no one knew what I was doing over the years, and when I had to jump out of the darkness appearing as a Ninja shadow to help those in need, all the criminals would see was the Iconic Ninja silhouette in which did send a shock through them, and this worked every time.
You see all it took sometimes was the Image and illusion of the Ninja appearing from darkness that shocked even the biggest men out there, my Martial arts skills where just for backup, no one knew the sword on my back was a foam bokken or was it?
