British police could seize kitchen knives if they believe the blades will be used to commit crimes, according to a proposal by U.K. authorities.

Britain’s Home Office also might ban some machetes and zombie-style, or decorative, knives, with harsher penalties for the sale and possession of the instruments, The Telegraph reported.

Those found responsible for moving such weapons — including belt buckle knives, butterfly knives and push daggers — could face up to two years in jail under the proposal. The current punishment is six months behind bars.

“The thugs wielding these deadly knives aim to terrorize their victims and the public, and too often even carry out horrific or fatal attacks,” Home Secretary Suella Braverman said, per the newspaper. “They are emboldened by the cowardly idea that carrying these blades inflates their own status and respect.”
