That is the barrier that hard work and familiarization, and forcing oneself to use common sense, can breakthrough and a major reason that I spent so much time with the knife in the 1970s and early 1980s.
The aversion to knives is similar to the one about snakes, it is what leads some people to say that they would prefer facing a gun instead of a knife.
If given the choice of how my attacker is armed, gun or knife, my answer will always be the same.
If given the choice for how I would be armed when randomly attacked, I would always choose the gun.
When deciding how to arm my wife at home, I would always choose a gun for her, rather than a knife.
The knife gives you the chance to let the bad guy know that holding that thing, and killing you with it, are two different things entirely, that he still has to defeat you in a fight to the death, a situation where winter clothes, an area rug, a lamp, the broken leg off a chair, your hands if you are the type, can instantly switch the tables, or can win the day. There is a reason that a knife isn’t a huge deal in rough bars where the bad boys hang out.
When the bad guy (even if he is old, fat, weak, stupid, slow, or unskilled) has a gun, it isn’t quite so convincing or realistic, when you tell him “OK big boy, you have a gun, but now you have to find a way to get those bullets into me.
