You've got to look at it like this;
At two feet, the guy with the knife wins. At 100 feet, the guy with the gun wins.
At some point, the guy with the knife starts too far away to be reliable. This point is about 20 feet. This isn't to say all knife-guys are lethal at this distance, but that some could be. And it's better to err on the side of caution.
I don't like some of the suggestions here. Turning to run gives your back to an opponent who has a head start on you, and has a knife. Not good. Backpedalling, or side-stepping has a very high 'trip over and die' risk factor.
My personal plan of action, when confronted with an aggressive person with a knife, at this range, where retreat is not possible, is to drop into a fighting crouch and take things as they come. My reasons are two-fold: Firstly, Handguns are all but illegal in my country (Australia). The use of one for self defense is strictly prohibited. In a strange bout of insanity, our government also banned tasers, pepper spray, and even airhorns. Secondly, it's what I've been trained to do.
Twenty odd feet should be the cut-off point. Counting on drawing from a concealed position, with the adrenaline dump, and stopping the other gun in perhaps two seconds, three at the absolute most, is very very risky.
If you want to really test this out, you can't just stand there and draw as the guy with the fake knife rushes at you. The situation fails to take into account the adrenaline dump you'll be experiencing. Instead, go for a two mile run, do fiteen press ups, and immediately run the test. The shaking, weakness, loss of fine motor skills, elevated breathing and heart rate will mimic closely the state you will be in if you ever need to draw and fire like that.
