Kujang for comments

[Gonzoadler]

Hello,

I received this Kujang, your comments are welcome. The handle is carved in the shape of a tiger, the scabbard is decorated with a tiger's head and a paw as tip. The blade shows a nice pamor pattern.
dimensions: total 45.5cm; without scabbard 36.5cm; blade 22.5cm
I have some questions about it:
- How old could it be? I think it is not very old, but I'm not sure.
- Was this weapon only used by the Sundanese people?
- My Kujang blade has 7 holes. In this thread I can read that this refers to the seventh month of pregnancy: http://www.vikingsword.com/vb/showth...ghlight=kujang
Is this right or are there other possible interpretations?
