Thanks for the input. 
 
Maurice -  The way the handle is shaped seems to suggest a figural head in profile (I'll try to take better pics when I can).  Do you know if this intended to be representative of something? 
 
Amuk Murugal - I'm leaning towards referring to this as a Tenegre rather than a Binagong, the distinction being a flat or forward curved blade on a Binagong whereas the Tenegre has a bellied (convex) edge.  This is how I think of it for myself, but I'm not sure if this generalization is appropriate or not...   
 
I am still curious about the markings on the back edge.  I know that it was often a simple matter of ornamentation, but the sparsity of these marks made me curious if there was some other meaning.
