Only a handful of stabbings have been reported in other countries. On Dec. 14 – the same day as the Newtown, Conn., school shooting – a knife-wielding man attacked students at an elementary school in central China, wounding 22 children and one adult.

Unlike recent high-profile attacks where guns were used, Tuesday’s incident likely won’t lead to national debates on knife safety or tighter regulations on their sales, said James Alan Fox, a criminologist at Northeastern University in Boston.

“Knives just don’t create that same sense of fear,” he said.
