You are safer without a knife

[Big King Sanctaphrax]

I think whether running is a good plan depends a lot upon the nature of the conflict you're in. If someone threatened me with a knife and demanded my wallet, I reckon I would probably attempt to run, as chasing me down over a distance would seem a lot of trouble for a few quid, and they have no stake in actually hurting me per se-they just want my money. However, if the aggressor's objective seemed to be to injure/kill me, it would be far less clear cut.

As others have already pointed out, these stats are confounded by the fact that people who carry knifes are much more likely to be involved in nefarious activities that would increase your odds of getting stabbed. I would like to see a breakdown by type of knife carried, though. I imagine that the incidence of stabbings is far higher amongst people who carry Crocodile Dundee-style machetes than amongst people who carry little penknives.
