I happen to have an example of executioner 's sword.
It 's the 3rd one from top. The sword was used by an executioner 100-150 years ago in central Thailand. It was kept by his family and then transfer to a collector.
By handling, it 's a little heavier than ordinary type. It could be because of that its POB 's a bit toward the tip. My feeling 's the sword 's definitely made for hacking job.
