This video was filmed in October 2014 when I was teaching in Canada. This clip covers the bunkai for the end spin of Chinto / Gankaku kata.
It is obviously a potentially dangerous technique and it should only be practised under the supervision of a suitably qualified and experienced person.
It is presented here solely as an explanation for the motion found within the traditional kata. All viewers are encouraged to be aware of and to adhere to all local laws relating to self-defence.
All the best,
