To put it blountly, Americans like to stab things. You give any American male, of any age, a sharp object, and the very first move he will make is imaginary stabs, followed swiftly by looking for something real to stab. And then to overhead downward full power stabs.

Even in normal cutting, they will push point first and just keep pushing. They also grow up with knives where they crowd the hand right up to blade, and use ricassos for finger rests, and need something, even just a bump or finger groove to keep fingers from slipping into blade.

In short, most American males do not know what they are doing with a knife, and are a danger to themselves and everyone within a mile. Hunters, and cooks, know how to use them, often self taught, but most only play with knives rarely, most knives illegal to even wear in major population centers where majority lives today.

For a generation, now, they have not even been able to carry a pocket knife during almost entire childhood, as even a photograph of a knife can literally get one suspended from school. An emasculated entire generation, and by the pen and not the sword.

It would be a nation of one-handed males were it not for guards.
