“ Knowledge Will Always Forge The Sharpest Blades"

"The Way Of The Sengoku Warrior"

"There Are No Second Chances"

Strength of mind and flexibility of limb are the keys in order to obtain speed and power through defensive and offensive actions. Like a samurai’s blade the secrets of its strengths relies on the blending of different grades of steel. An inner core of steel with more carbon than the outer cutting surface with less carbon, making the sword flexible and hard at the same time. Blending of these elements takes time and great skill in order to produce such a deadly weapon. "Practice to develop this power in you" it will take time to blend skills of hard and soft, but do not be fooled in believing that outer strength alone is all that is required in combat, this will only encourage tension making movement slow and predictable. Flexibility alone will give great speed and manoeuvrability, but is too weak and ineffective against strength alone. Blending both will give not only inner core of flexibility, but an outer strength like steel.
