Knives, including small pocket knives, are only allowed in checked bags. Only plastic and round-tip butter knives are allowed as carry-on blades. Most bladed items are allowed in checked baggage, including scissors, razors, swords, axes, box cutters and blade tools, if they are properly wrapped or sheathed.
You can carry in your checked in luggage but not in ur hand baggage. But airlines always have the last say. And even if u r carrying make sure you pack/wrap it in a plastic cover or a zip lock bag.
