I think that Acronym, should understand that some Karate schools, base their training around the ability to fight.
Not all schools went the route of early days point tournament, not that it is bad, but training changed and a lot of the combat side, was left out. Karate has never been, just about Kata. There are some schools that tend to be focused more, on the fighting aspects.
We in our school, still practice the same basic bunkai, as we did in the early 80's. There are 13 kata to black belt and about 75 bunkai to learn. That is just the base, but there are 3 ways that they are taught. The last way, is sparring semi full contact, only using specific bunkai from a specified Kata. That is simply kata sparring, just one of ways we spar. Really, from these basic bunkai, the student is encouraged to build off of the basic patterns. But they must know them individually and in the basic form, and use them individually, before combining anything.
This is how, I learned it in the 80's and still teach, but that is different from the Free sparring that we do. That, focuses on distance, basic kicks, strikes, knees, and really just about anything needed for a well rounded fighter. Including takedowns and grappling. Yes grappling on the ground, quite a few styles have a ground game, another one where the basics haven't changed much since the 80's, but we always grow and seek new methods of training.
This is a small part of the Karate I trained in the 80's, and a small part in how I still train and teach till this day.
But, I am a Toyama Kanken line, and although being a Karate-ka, he traveled to different places and learned various arts and he incorparated many different concepts into his personal system. And, encouraged it in his students as well. I posted a picture of an old article from 1949 in an earlier thread where Toyama described karate as a mixture of Jujitsu, boxing, fencing and wrestling. It shows, a well rounded Karate method. Again, from 1949...
In his words "Karate is whatever you make it".
Karate is just a word a basic description. It of itself, is not one method set in stone. Its an individual method that grows however you individually choose.
Honestly, it seems as if a lot of people that walked away from karate, just wanted to learn how to damage an opponent, instead of controlling the opponent. Although there is an art to destruction, the true art is in control.
Just a little history of the Karate I learned 30yrs ago and continue to learn, and how some of us dug in and hung in there, and will be here 20yrs from now.
