Denis-handsome knife and sheath, full featured, but simple: well done.
Cfraser: Charitably, tie-downs provide a means for securing the sheath to a backpack, packbasket, land rover cockpit, whatever. Less charitably, leg-ties provide an element of tactical coolness, a gunslinger look. IMHO, belts are awkward places to carry belt knives, canteens, handgun holsters and flashlights, a bother justified only by necessity in combat and law enforcement/security scenarios. YMMV.

...and if I wear my knife on my belt, how will I carry my sword?
