What are these woodworking techniques?

If anyone could tell me the name of these techniques so I can research how to do them it would be great. Any extra information would be nice too.

Firstly, I'm looking at the lid's of wooden boxes. They are made up of 4 edges that touch diagonally, with another piece of wood in the centre. In some, on the underside of the lid there, the edges are thicker than the centre piece, so there is a gap. Examples: This and this

Secondly, these boxes with the metal (over joints?) Example

Are they just metal pieces covering joints like this or this?
