A Patchogue man was arrested at Kennedy Airport after authorities discovered a trench knife and several other blades in his carry-on bag, authorities said Saturday.

Port Authority police spokesman Joe Pentangelo says Timothy Schiavo Jr., 29, was charged with two counts of criminal possession of a weapon.

Police said Schiavo also was carrying several scissors, a number of lighters and matches. A trench knife has metal knuckles on the handle of the blade.
