Knife defence: 1) stay alert 2) practise running 3) scream to get attention 4) use your enviroment - ie. rocks and sticks....i wonder what's more dangerous, knife or me pitching rocks at my attacker at 70mph+ 5) use your words and fight dirty -eg. "please dont hurt me!!!" then proceed to kick his crotch when he's off guard.... 6) know your attacker - a homeless man started fighting with a friend of mine, they were in the pushing & shoving stage when my buddy decided that he did not want to fight a homeless man - armed with a squeegie. LOL So what does my friend do?? offers the man a beer ... and things go smoothly from there on.
