Thank you!
			 
			 
			
		
		
		
			
			I appreciate your input. 
 
Yes, the rounded end of the blade is sharp. 
 
I've tentatively identified the top blade as a bolo, which I realize is a very broad term.  As noted, the grip is indeed a socket that would allow attachment of a staff to create a spear or polearm. 
 
What expertise I have is firearms related, which is how I came to my volunteer work at the museum.  I am learning a great deal about Asian weapons but remain woefully ignorant and have only scratched the surface. 
 
Again, thank you for your assistance.
