Japan and Knives

A man walked into a convenience store and pulled out a knife on two female shop attendants - "give us the cash!"
One of the shop assistants aged 51 pulled out a kitchen knife, held it up to the assailant and said...
"Society is rotten because of fiends like you!"
The man then decided to make a run for it empty handed.
While some regions have societies of guns, Japan is definitely a knife society.
News via Spoonichi. I didn't have a pic of a 51 year old woman with a kitchen knife so here is the next best I could do - school girl in pool of blood with knife from Neta.
