When I was eight, I was given a "lensatic" compass, an OS 1:25000 map of the local area and a Swiss Army Knife. I still have the last but unfortunately I've lost the other two. Good presents, though I can't remember now if it was birthday or Christmas. I do have a little compass on a key ring with built-in thermometer. The thermometer is totally useless, there's an air bubble in the mercury column, and the compass is pretty random too.
