ive broken a few, but the last one i broke, wasnt the shafts fault. i was seeing if i could split a small chunk of wood by shooting it with a nail head field point. got pretty close to doing it. still gotta watch out with bamboo, its pretty tough even when broken.. someone mentioned that it was used in the past with it just split for mail targets.. i can believe it. just take a piece of bamboo and shot something, like a board with it, and see what it does..
