What is the usefulness of a crescent kick?
I have hung around here enough to discover that a lot of traditional martial arts training methods (specific stances, kata, etc) are pretty handy when you recognize the intended use of the "moves". For instance, during my ATA tae kwon do days, there was this stupid double up-down windshield wiper looking block that I thought was useless. My instructor showed my how it was actually an arm wrap that could be turned into a wrist lock/kimura/ude garame. And a long TKD/Karate front stance is basically the position a proper tai otoshi requires.
I have been wondering if there is a point to crescent kicks. Granted, they helped me get useless zero-contact points for head kicks during ATA sparring. But they don't seem directly useful in combat. At crescent kicking ranges it seems like punches, elbows, and knees are way more effective. But I do think it helped me loosen my hips and learn the looseness of leg that a MT style low kick seems to require.
Any other ideas about the "real" use of this "kick"?
disclaimer: I know shogun and others have landed crescent-like tornado kicks. So maybe they are more effective kicks than I realize.
