Brutal, deadly, overkill, street effective. These and many other such terms have been used to describe the martial art system known as kajukenbo.
Kajukenbo gained it's reputation for being brutally effective decades ago in the U.S. Territory of Hawaii. In the Hawaii of the 1940s the enemy was not the ancient battlefield soldier, it was the common street criminal. Instead of swords and spears he armed himself with knives, clubs, and guns. Even when unarmed he did not fight by any rules. He punched, kicked, gouged, bit, and stomped. If you encountered one of these brutal street fighters you were in for a life or death battle. Kajukenbo was designed to win such a battle.
