We've had discussions on fundamentals and advanced techniques, etc.
You uechi type people have this sanchin kata which seems simple to see, but advanced uechi type people insist that it is very advanced, once you get to know it.
Well, here's the deal. I don't know the japanese names but there are a bunch of Japanese, Korean and Okinawan styles who use these "blocks" that are directed downward, to the middle, and upward. I think they might originate from shorin ryu, and beyond.
So what I'm finding is that these movements are extremely powerful and versatile.
There is definitely a huge difference in how they are usually demonstrated in kata, and how they can be actually used using body weight to project force
Maybe something to look at for those who find themselves at a plateau, and are looking for "advanced" karate.
I have come to the conclusion that much of what is taught at the beginner stages in some "styles" are actually those things that are most important for the student to really get into, and understand, if they want to use their body as a weapon.
I guess what I'm trying to say is there are these basic movements that are usually only demonstrated in kata and don't have any tactical value in sparring, which have an extremely violent potential, if seen for what they are.
And what they are is not "blocks".
Which isn't to say that they can't be applied to the boogeyman's arm as he jumps out at you from an alley.

More like swinging a baseball bat than trying to "block" an attack.
