Why don't we see any other Klingons wearing sashes like Worf to denote their houses? For example in Soldiers of the Empire none of the Klingons aboard the Klingon ship are wearing sashes. Why? The writers even go out of their way to explain why Worf isn't going to wear his sash at the beginning of the episode (because the house of mogh doesn't exist anymore so it would be pointless in front of klingons) but that doesn't explain why we don't see any other sashes. Correct me if I'm wrong, perhaps I'm forgetting something, but I don't remember any other sashes on klingons in ds9. Except maybe Gowron once or twice.
