Hello Drac2k, I am in agreement with Detlefs opinion on age and origin of these pieces. I also agree with Carlos, great knives. I can tell you that I would be quite happy to be able to add any of these pieces to my own collection. Just to be a little different I would like to add that my favorite is the first (top item) in your first photo. Very interesting blade style that I do not have an example of in my collection. The bottom dagger as Carlos stated is also a very nice piece. The rather unusual Visayan knife with the figurative hilt has some very interesting features like the blade being beveled on what looks like both sides. Can you post a photo of the end of the hilt on this piece as it looks in the photos that it might have a flat surface. Again very nice additions to your collection and if you get tired of looking at them please feel free to send them my way.
Best,
Robert
