998 knives were seized in Dublin last year - which is almost half of the country's total.
2,243 were recovered by the gardai in 2020, which is 5% more than the previous year.
172 were seized in Cork City and 86 in Co Limerick.
Dublin Central TD Gary Gannon says the number of knife seizures in the capital city is 'massively concerning'.
"The streets around Dublin are too often unsafe."
"That comes down to a multitude of factors, it comes down to the poor street lighting, the dereliction."
"There are people on the streets with knives and ready to use them in some instances."
