I'd also add that the suspension loop on the back of the scabbard seems
far more suited to hanging from a wall than from one's belt.
Furthermore, the (awfully) flat back of the scabbard is as flat if not flatter than the sgian dubh scabbards which unlike dirk scabbards are actually meant to be worn agaisnt one's skin, though again, such a design would be perfect for hanging on the wall.
