A thief swiped $2,000 in designer items from a Manhattan Coach store over the weekend — and flashed a box cutter when an employee tried to stop him, cops said.

Video released by cops Monday night shows the suspect strolling through the open door of the store on Fifth Avenue near West 54th Street around 6 p.m. Saturday.

He begins to pluck several items off racks before making his way to the exit.

A 31-year-old woman working at the store tries to intervene, but he whips out a box cutter before taking off with bags and clothing worth about $2,000, cops said.

No one was hurt, according to police.
