My system of FMA assumes the sword is the first, and primary, weapon. Learn the sword, and everything else will follow.
Other systems leave the sword until last, or separate it into it's own special section. Most FMA styles start with stick, move from there to empty hand, and then to edged weapons, maybe, last of all.
There are many reasons for the order in which things are taught, and each series has it's pros and cons. It's taken a long time, but I can understand, finally, why it is the way it is in my style - sword first .... well I should say I 'might' understand, after all it is only my opinion ....
I've written before that the sword is a singular weapon, it really is! Disregarding all the variations in usage due to shape and size, edged weapons have one thing in common - if you are holding one, your opponent will think twice before entering into your space. Even if they are twice your size and they can break you like a twig, even if there are more than one of them, you still have time, and the possibility, of averting taking damage if you are skilled enough and smart enough.
So, it follows that if holding a sword takes power and force out of the equation ..... what else is there?
Well, obviously a more tactical game, and given the presence of swords there is now the space to explore these other universes, a space much harder to find when there is no real threat to keep an aggressor out*.
So, a place to discover tactics for when you are faced with an overwhelming force, when you are at a disadvantage, or seem to be facing loss.
A space to learn about psychology, hooks, triggers, and threat, of danger and cost and the price of victory. None of which is possible if you are too big and strong to contemplate needing it, or too small and weak to even imagine that the possibility exists.
Sonny said: "Accuracy first, then power, then speed" - A recipe for upping anyone's game, even those who rely first and foremost on power and speed, but especially for those that have neither.
*The other great forum to practice tactics without power and speed is in the grappling arts, but they are limited to the tactile variety as they work from contact.
