User blog comment:AYET/Why is Buggy not dead/@comment-9673311-20150309174307

soon no one is going to figure out that he did not have to use  haki

1. Luffy did not know what haki was at that time are know how  to control it and that's why he  did not use it

2.he can use his blade to cut up Luffy without using haki because that was one of Luffy devil fruit weakness

3.because he did not use haki against Luffy and that's why  when buggy get cut he did not die
