Here are a few from the Philippines. They are probably in the letter opener class except one that I'm not sure what it is. From the left a Spanish influenced Dagger that has Port Sual Luzon scratched into the grip, length 7" The next is a Garab, length 6-1/2".The next a Talibon, length 7" and the last I don't know what to call,

length 8-3/4". It is much better made and sharp enough to be used as a razor. If anyone has any ideas on the last one please let me know. Thank you.
