Well, It's going to be for a film. The blood from running yourself through might be a little excessive.
I agree. It's extremely intense. I have a different film which can end no other way then a knife fight. That one I have to shoot in Peru though. The knife suicide a little tacked on for this one I think. As long as your not thinking of killing yourself, the most efficient ways with a knife are to stab the kidney and to slash the carotid artery.
Back ideally, side nearly as good. Your fine motor movement will be impared when you are in a survival atmosphere unless your an experienced killer. I'm not. Your whole goal with a knife is to close the distance. Once you are in close enough aim for their back and side, and hit several times. This is if you want your opponent dead, which is the purpose of drawing a knife in a fight. I took Jeet Kune Do, and I know like 7 hit knife strikes, and they work, they were just pointless as compared to Krav maga's very simple eloquent methods/ Get your opponent close, reach to them as if you were ballroom dancing (imagine grabbing their hip) and strike them in the kidneys. They will no longer be able to harm you and they will bleed to death. There are non lethal knife fighting techniques too. But I don't honestly see the use in them.
pulling a trigger on yourslef. you can jump and regret it for a split second. somethin with the gun in your hand is real to me.
i think the whole romeo and juliet, when i think of a romantic way of killing yourself, not being able to bare living because of the loss of your true love, and taking the poison and slowly dying, staring into the eyes of your beloved, so that is the last thing that you see before you pass. damn, thats making me hot! lol.
