There will always be an exception to just about any situation or example. The point I am making is that out of the thousands of people practicing a weapon, what percentage will or hava used what they are practicing? Then out of that percentage what percentage has had it not work for them? I don't know the answer but I can bet the numbers are really low for both questions. That is all.
You could say the same thing about unarmed fighting. Out of the thousands of people studying TKD, most will never be in a real fight. and of those who have, there are plenty who have had it not work for them, so there iis no point making the distinction with weapons.
In any case, the weapons training grafted onto most TKD classes is generally of a much lower caliber than the TKD classes themselves and only serves to keep people interested and give them something new and cool to learn.
Most people looking out the window right now won't see anyone carrying any weapons (swords, bo's, nunchucks, sai's, tonfa's) with them.
I see more people with sticks than I do with guns, but I am sure that you would not consider training in the use of a firearm to be a waste of time.
Having said that, every cop or security guard that you see carries a tonfa or a billy club or similar wooden striking instrument or a multi-cell flashlight of the same length. Every tow truck driver has a nice iron bar of approximately the same length. Last I checked, half the adult population carries a pocket knife.
The subject of improvised weapons has already been mentioned and you dismissed it because it did not work for you.
Effective weapons training is not about becoming expert in a specific weapon or weapon group, but about learning the principles of weapon use. If you
effectively train in multiple weapons (as weapons, not as showmanship aids), the principles become clear. No swords, bo's, nunchucks, sai's, tonfa's? How about newspapers? Magazines? Ever beat up someone with the New York Times? Rolled up a newspaper can be used as an effective weapon. How about that flashlight? How about a cane?
Very few people receive truly effective weapons training. Effective training means sparring. Free sparring. Unchoreographed sparing. If the program has no sparring or nothing but one steps, then it is not an effective program. It may be traditional and authentic to the extent that its practices are authentic, but without some kind of free sparring, it is ineffective for teaching you to use the weapon to defend yourself.
For those of us who do receive effective weapons training, I can assure you that it is not a waste of time.
