Hi all:
I will agree with Moro Moro to a point. In my experience, all things being equal, if you have an equally skilled empty hand fighter against an equally skilled knifer, I think the empty hand person will lose every time.
My reasoning on this is simple, the gross motor movement and effort required in order to disable an attacker with the empty hand is much greater than that necessary with the knife. A good knife simply has to touch the opponent in order to do some damage. In panic, the person facing the knife may do more damage to himself by thrashing or pulling away violently to escape the blade. Against a skilled knifer, you will get cut, multiple times and probably seriously enough that if you don't die immediately, you will probably die if you don't get to a hospital very quickly.
That being said, I've been taught you learn empty-hand knife defense in the hope that the person you're facing doesn't really know what they are doing, which will hopefully be the case. However, if you treat every attacker as an expert (and you have good, effective training), you should be able to do the best that you can in an empty hands vs. knife situation.
My reactions to confronting a knife are in the following order:
1. Run - if at all possible. There is no honor being face down in the gutter or face up in a hospital bed with HIV, Tetanus, etc... just because some fool wants to use a knife on you. Run away!
2. Try to create an opening or distraction to either run or get the situation or my advantage if I'm stuck.
3. Fight for my life with every means at my disposal until the attacker is disabled and I can escape to a safe distance as soon as possible. When someone draws a knife on you, you have to assume that they mean to kill you. Anyone who learns good knife-fighting technique or has faced a knife down/been cut before knows that it is a serious, life-threatening emergency and should be dealt with as such. Note that escape as soon as possible bit is important as trained martial artists can end up as the murderers in these situations if you continue to stomp the attacker's head to a bloody pulp on the sidewalk after both his legs and knife arm are broken, he/she's unconcious and you have the opportunity to escape. If you can get out, do so as soon as possible.
Just my opinions on the subject, but I do agree with parts of what everyone has said so far. The worst thing you can do if attacked by a knife is to just give up. In my opinion, if you're going to go down, it's always better to go down fighting. It might make the difference between life and death in this situation.
Itotally agree with Mr. Castro and his post above. Most people in the US have been fooled by movies where the knifer gets the blade kicked from his hand or disarmed simply since it is "just a knife". The movie 'The Hunted' may change that perception somewhat (High Art/Exposure is little known except among folks like us nowadays). As for laughing about the knife as a gir'ls weapon in the PI, I find that a little hard to believe if you don't have a longer blade or yantok/baston available to you when you face it.
Good discussion!
Thanks,
