Knife Hand Block (Tate Shuto Uke) in Rooted Stance (Fudo Dachi)

Turn your head to look towards the 10.30 clock position
Breathe in through your nose
Move your Left foot in towards your Right foot
Slowly step forward with your Left foot towards 9 o'clock into Fudo dachi.  This will give you a wide stance facing the 10.30 clock position.  Make sure your Right rear leg is bent and the Right hip is pulled back slightly

Bring your Left open hand to the shoulder and as you step forward into Fudo Dachi, slowly push the hand forward towards 10.30, the outside ridge of the hand away from you
Keep your Right fist on your Right hip
Breathe out slowly and strongly through your mouth during the technique, which should last 2 - 3 seconds. 
Tense all your body muscles for a brief moment on the completion of the move
