The Cane in the 5th Grip: Thrusting with the Hook or the End

I am holding the cane as shown (with one third sticking out at either end).

I am thrusting with the top of the hook or the end of the cane.

I have the hook turned into my body allowing me to strike with the entire back of the cane.

However, I have to be careful to keep my elbows in and the cane out from my body.

Otherwise, I could drive the hook end into my back.

It is actually easier to see on the video than to explain in print.
