Okay, but if you have other tools that can perform that function (not the least being the exact same kick with the toes extended, which some styles ALSO use), then what's the issue? You're very much overgeneralizing Karate. There are a lot of differences between styles, so there's not just one "Karate roundhouse".This is my point. If you train Karate roundhouse kick instead of MT roundhouse kick, your tool will have less function to perform.
The MT low roundhouse kick can be used to
- hurt your opponent's leg, or
- function as a foot sweep.
The Karate roundhouse kick can't be used for that function.
Does Karate "low" roundhouse kick (to hurt opponent's leg) even exist?
