This discussion is getting close to the borderlines of acceptable content for the board(If I remember the rules correctly), but, given that, I would feel remiss if I did not commit on this...

If you are going to pull a knife, you had better be afraid for your life... If you are afraid for your life, you do NOT pull out the knife and try to scare them off, you pull it and start stabbing as fast and viciously as you can and try to put as many of them out of commission as you can, and then RUN. If they are not expecting it, you should be able to take three or four of them out before the rest catch on to what is happening, and it you are acting crazy enough they will likely want to get away from you... This is assuming that they are not hardened gang members... If they are, then YOU would likely have a knife in you as soon as they surrounded you, if they were intent on killing you.
Remember, you NEVER want to get in a 'knife fight', what you are trying to do, is save your own life, by whatever means possible. You do not want to try to injure them, you want to put them down... But remember, you are NOT trying to kill them, you just want them to be out of the picture, whether they are dead at the end of the day is of no consequence. Only whether YOU are alive.
