Lancrastian Army Knife
The creation of Shawn Ogg, advised by King Verence II. A small device for everything a soldier in the field needs, like nose-hair tweezers.

There is another annotation worthy of remark here:- Queen Victoria's consort, Prince Albert, interested himself in the minutiae of the running of the British Army to such an extent that he plagued his wife's generals with a barrage of wholly impractical suggestions, which had to be tactfully lost or otherwise fended off, as not even a field-marshal can tell the monarch's consort where to get off with interfering in the work of the professionals. Albert was allowed one or two little triumphs, such as the adoption of his design for a piece of campaign headwear, but was in the main politely sidestepped.
