be smart, use blade only if they step into your house,
i kena before, neighbours (tiong wife and sinkee hubby) came at 2 am kpkb (they got the wrong neighbour, tot we made noise at 2am, was actually the one staying on top)
i took a chopper and waited and invited them to step inside, they kpkb outside my door
in the end, they called police and all land up in police station at 3am
they could not press charges as i was inside my house and i did not slash anyone
but the police sargeant said they could charge me with 'criminal intimidation" if they want
lesson learnt was.... small matter dont lose temper, cant imagine if i slashed him, land up in jail for nothing
want to do, go all the way and kill, at least $5 million then do this type of thing, if not really boh hua
