I'm not a scout either, but the very practical horizontal behind the back carry method is commonly called the scout carry. The straps in the middle of the sheath allow you to wear it that way. It is an excellent carry method for any time you are carrying a 711 sized blade in the outdoors and don't plan to sit in vehicles or chairs much. It places the knife out of the way of almost everything, including most packs, yet keeps it within quick easy reach, all while not adding extra weight/bulk to a leg.
It can even work for certain types of larger knives. This is the most comfortable method of carrying my TTKZ due to it's curved design keeping it behind the body, though typically you wouldn't carry a knife that large in this fashion.
