I picked this little sticker last week from a collection of predominantly SEA edged weapons. One piece of metal measuring only about 9 inches in total length; the blade accounts for about half of that.
Wedge-shaped/triangular cross section with a flat 'grind,' with a rather thick spine (about 7mm) for its size.
I'm familiar with the small, curved ring-pommeled knives shown in Zonneveld, but this doesn't seem to resemble it. The blade has a 'feel' that suggests the (northern?) Philippines to me, but again, I haven't seen one similar.
Any ideas?
