What are my avenues of escape? What kind of size/shape is the person coming at me? How are they approaching (ie what physical and mental skills characteristics are they exhibiting)? What act of God took my gun away from me? How am I dressed. What else is around me? etc, etc, etc.
I would usually try to avoid a knife fight if at all possible...I'm more competent unarmed than with a short blade. However, if I was forced to I'd wield it weak hand, reverse grip, blade out (kind of like an edged tonfa) and use it primarily defensively, stabbing only for an assured kill.
Well this scenario was completely fictional but here are the details if it occurred while I was on my normal walk (which is what made me think of it)...
You are walking across a closed elementary school at dusk.
The person coming at you is in clothing that makes it obvious he isn't carrying a gun. (shorts and a tshirt or something, after all it is California

He could have a small knife on it but isn't reaching for it. Nobody else is around. He is in shape and about your size.
At 25 feet away he yells something like "I am going to kick you ass!" and starts a full sprint toward you. Seems to have his wits about him and doesn't seem drugged up.
You could run but it would be at least 200-300 feet to an exit in the fence that surrounds the school. Nothing useful is around you and you are dressed similarly to the guy running at you.
Your knife isn't a cheap pocket knife. It is a Cold Steel Voyager VG-1 stainless locking knife with a quick open nub. I can pull this knife out of my pocket and have it open in less than a second.
After reading the responses I think I would try to make it the 200-300 feet to the fence exit. If he reached me before that I would try to get the knife out and use it without him seeing it.
