While true in the abstract, somebody who uses a knife is more sure of
the results than a person handling a gun.

That is proven by the statistical fact that at a range of three feet, more
people are stabbed than wounded by gunfire. It is truly amazing that at
arm's length, a person can miss with a gun, but have better luck with a
knife.

Another thing that has not been stated: a knife is infinitely more
intimidating than a gun. If you can put some distance between you and the
perp, the dangers from either a knife or a gun drop exponentially. But up
close and personal in a fight where the two combatants are not ever
disengaged, a knife usually wins, exacts more damage, or leads to lethal
consequences.
