Dagger For Identification

[Robert]

This is another dagger that I've had for a few years now. The problem I have is trying to figure out if it is Spanish Colonial Philippine or something else all together. The sheath that came with it looks like one from a tombak (woven band at top fishing line at bottom) but fits the blade perfectly. The blade shows an inserted hardened edge and some damage and signs of resharpening close the the hilt which throws off the blade symmetry. The hilt itself is made of a dense hard wood instead of horn. The guard and pommel are cast brass. The other strange thing about the guard is that the quillons are dove-tailed into the central section. My guess is that this is an old repair as it seems to be to labor intensive for any reproduction knife. The tang goes through the hilt and is peened over. Comments welcomed.

Blade length 9-1/2" measured from the brass to tip
Blade at thickest 1/4"
Blade at widest 1"
Hilt 4-1/2"
