When I worked in the display industry, we did a lot of work with knock-down fittings. KD fittings allow you to build a project and ship it in a disassembled configuration; stacked flat panels, for example. When the pieces come out of the box, you then assemble them. One only needs to buy something from Ikea to know how that works. Almost everything Ikea sells comes packed in a box and needs assembly. Often there is an Allen wrench included to tighten the fittings or, perhaps, a Phillips screw driver is required.
