How do you "deploy"?

[Robert.B]

I wonder is criminalizing knife carrying in the UK would be as effective at stopping violent criminals from carrying knives as banning guns in the USA would be at stopping criminals from carrying guns? Make them illegal and law abiding citizens wont carry them, if only criminals are carrying then that makes us all safer how?

its criminalized in australia, I have been carrying since i was 12 years old though and do not intend to stop a knife is a tool, technically so is the government but i know which of the two is the sharpest tool in the shed.
