It's like this....you will use what you know, use it with the greatest intensity (force) to get the situation resolved, regardless of style, technique, ancientness, sportiness, combat-effectiveness, or whatever. These various skills are no different than the EDC/PSK you carry. You have to make do with whatever you have.

Final note: We were talking about a 3-yr old, now 5-yr old. They need to learn to make alot of noise when approached by a stranger and run like mad when they do.
