I was curious because Shanks was cracking parts of Whitebeard's ship just from his presence, so couldn't that mean if mastered enough it could have more of a destructive power to physical objects instead of the mind when mastered enough?
From the fact that "Channeling a haki, able to produce the more power", I don't think so just simply releasing it 360° from your head would do any good damage! Even mastered haki user Shanks could do so far!
But yes, channeing that same energy of Conquer Haki into your sword can swinging it, probably can destroy a island to half (if you chaki is that much powerful)!
