Hello, 
 
Thank you David for your comment, 
maybe it's amberoid as you suggest, maybe mixed, some parts have translucence and are brown with no light, other nothing at all ( cf pictures ), 
 
for the blade I put some pictures, really don't see/think it's made of two sheets but it is really thin compared to other jambiyas I have and has a really sharp edge 
 
Kind regards
