Take your blade and tie the handle to a cord about thirty centimeters long. Hold the end in one hand and flat out your palm and backhand against the blades flat a few times. Now lift it in your hand a little bit and move the rope so the blade follows the natural lines of that you created and move accordingly to avoid harm. Do the same for the forearms and arms and play with this while sitting, flat on the ground, standing and walking. This works great for your awareness and sensitivity weather your eyes are open or closed and do take care not to injure yourself. Put a bit of tape on the edge or use a dull knife until you can handle the real thing. Remember there is no replacement to the real thing so seek an instructor or friends to work with you and make all of us better.
