Can be very dangerous: https://www.bbc.co.uk/news/world-asia-india-37115032

Actually, a large kite (I know fighters are not large) can be dangerous without glass on the string.

i barely see kites on my neighbor nowadays but when i was a teen, we had a group that never fought with each other and our signature against other kites nearby was (translated directly) to shout "fall out thrash!" when we cut/captured them. some got pretty mad at us. we had various techniques like bringing their kite closer to the ground and then someone throwing a line with a stone at the end over their line, so we could capture it etc. if i'm not mistaken we even slingshot some kites as a way of disabling. my record was to stay up after 8 won battles. that day i felt heroic hahaha

this reminded me of my childhood.

Can you recommend some specific ones?
