Figures showing a 35% rise in convictions for carrying a knife in public over three years are "deeply concerning", an MLA has said.
According to the Department of Justice, 220 people were convicted of the crime in 2019, up from 163 in 2017.
Worryingly, there were also two convictions for carrying a knife on school property.
During the same period, there were 260 convictions for possessing an offensive weapon with intent to commit an offence, with 87 of these occurring in 2019.
The SDLP’s Dolores Kelly, a member of the Policing Board, said she would raise the matter with the PSNI and Justice Minister Naomi Long.
"These figures are deeply concerning and point to a substantial increase in people carrying blades in public," she added.
"Those carrying knives are up to three times more likely to be injured in a stabbing incident. They are placing themselves and others in serious danger.
"I welcome the increase in police action on these crimes and in convictions, but it’s clear that we need to do more to deter people from carrying blades. I’ll be raising this matter with the PSNI and the Justice Minister."
Green Party MLA Rachel Woods, a member of Stormont’s Justice Committee, said while the focus on knife crime was welcome, it should be seen in the context that most local violent incidents involved people being physically assaulted.
"However, an increase in possession of bladed weapons should be met with an appropriate response," she said.
"The PSNI does some great work with schools in educating pupils about the dangers of knife crime and firearms.
"The Scottish Government has been innovative and tenacious in tackling knife crime. The Scotland Violence Reduction Unit has been successful in driving down knife crime through prevention and engagement, which is something I believe we need to adopt more of here.
"One death from knife crime or a violent incident involving a bladed weapon is too many and has a huge impact on victims, their families and society more broadly. Let’s learn from the success of others to tackle knife crime and keep people safe."
Justice Minister Naomi Long said: "The law in respect of knives, and separately offensive weapons, in Northern Ireland is similar to that established across the rest of the UK.
"The penalties available to the courts for such crimes are high, with the majority of knife possession crimes attracting a maximum of up to four years’ imprisonment and an unlimited fine.
"I take offences concerning knives very seriously and continue to work in conjunction with criminal justice partners in tackling this important issue.
"My department has no current plans to further legislate on knife crime or the sale of knives in Northern Ireland at this time."
