[Robert]

I beleave this dagger to be from the Philippines though I'm not quit sure. I would like to hear the opinions of the experts on this.

Blade lenth is 9-7/16 inches.
Blade width is 1-1/16 inch.
Blade thickness is 1/4 inch.
Hilt lenth is 4-1/8 inch.
Fittings are brass.
Grip is beautifully carved horn.
Tang goes through the grip and is rivited over.
Medial ridge on both sides of blade.
