Ring Pommel
			 
			 
			
		
		
		
			
			Hi Fearn,  
 
I have only ever seen one old dao without the wooden hilt and the ring pommel was actually part of the tang, extended all the way and doubled back just like a long hair pin so to speak, mayhap this was a one of a kind and they are attached differently but that's all I know. 
Well there you go, looks like a posted a nano second after Yu-ming.  There is a good example, slightly different from what I have seen. 
Yu-Ming, do you have any images of you dao's hilt prior to re-wrapping, they may show the ring pommel arrangement better?
