The top one is an example of knives still being produced in Myanmar/Burma (and, likely, Thailand). About 10 years ago, I was introduced to a gentleman who had a government-approved trip scheduled to Myanmar, where he was spending time with Karen tribes. I requested he bring me back something sharp and pointy if he came across anything inexpensive. He sent me this:
Dha-hmyaung. Myanmar (Burma). Early 21st Century. Brass and rattan fittings. Newly manufactured by Karen Tribesmen.
