Black Belt instructor David Gunzburg ass

Black Belt instructor David Gunzburg assists in the demonstration and is taken down flat on his back as Master Black Belt instructor R.S. Mitchell, owner of Mitchell's Martial Arts in Salisbury, Maryland, demonstrates "Cane-Fu", an acient form of self-defense using a walking cane on April 10, 2009 at a senior citizen home in Salisbury, Maryland. Mitchell and his team volunteer their time with seniors teaching the basics of "Cane-Fu", a non-deadly self-defense technique that uses the crook (the curved part of the cane) to help seniors fend-off attackers who only see a cane as a sign of weakness, but if used properly turns into a impressive weapon and builds self-confidence for seniors.
