Luzon or Panay?

Rob,

Here is another Spanish colonial knife from the Philippines. Unfortunately, the blade has been polished to mirror brightness by a previous owner. I don't think you would call this a "Bowie" but it does have a fairly large blade of about 10.5 in. and a guard. There is an unsharpened false edge along the distal part of the blade's spine.

And a straight version of the triangular cross-section blade. This one appears to have some age. I would say WWII era, perhaps a little earlier. Despite having a symmetrical double-edged blade, it has an asymmetrical S-guard. OAL out of scabbard is about 15.75 in.
