Saskatoon's police chief wants tougher rules for people who buy swords and machetes.
Clive Weighill said that police regularly see the weapons on the street.
And that concerns him.
"You know, we've seen people out at the fireworks out here in Saskatoon, and they're wearing their hoodies and they've got a sword shoved down the back of their neck," he said in an interview with CBC News.
"Well, why do you have to go watch fireworks with a sword shoved down the back of your neck? I mean, there's no law against it."
A 15-year-old teenage boy has been charged in Regina after four people were stabbed in a mall earlier this week.
Weighill said he doubts any law would stop events like that, but that the streets would be safer with fewer knives around.
He also make a distinction between smaller knives and the larger weapons that police often encounter.
"Whenever you get into this debate, people think it's so simplistic and right away it's "what about a kitchen knife? what about a paring knife?"," he said.
"Well, let's grow up. We're not talking about that. We're talking about weapons like this on the streets of Saskatoon."
As the law stands now, large knives can be carried in public as long as that person is not threatening others.
