TIP: To avoid damage to blades or handles in transit, wrap each knife individually in several layers of newspaper/bubble wrap, fully covering the tip. Wrap multiple knives together so they are not loose in the box using additional stuffing on the top, bottom and sides (using packing peanuts, bubble wrap or crumpled newspaper) so the knives are secured in the center of the box.
