Martial pioneer Bob Davies has passed away. Technically brilliant, encyclopaedically knowledgeable, uncompromisingly exact, frighteningly powerful, brutally efficient and unerringly resolute, he taught me that nothing is impossible. His biggest lesson: endure. A flawed man who provided endless inspiration, his lessons will live on in me, my brother and our students. He will remain one of the biggest influences on my life. He was my sensei.
