Sensei Duncan Hardy, moments after demonstrating the extraordinary skill involved in cutting an apple in half on Sensei June's throat at Clay Cross Gala in July 2009. The katana used here is razor sharp and Sensei Duncan has been performing this demonstration for over 20 years.

If you look carefully to the right of Sensei June's head, you can see the apple in mid flight.

The skill, practise and perfection required to demonstrate this art is beyond the reach of most martial arts practitioners.

Do not try this or attempt to copy any of these demonstrations - there is a risk of serious injury!
