There tends to be some favoritism going on in these tests...
often in favor of the nihonto...
it is like when Greyhounds are shown to be faster than Cheetahs oftentimes, but people like the idea of the Cheetah, untamed and fast as hell. But Greyhounds can be just as fast if not faster.
Like-wise people seem to hype up the Katana and say it will cut with ridiculous ease, etc... a sharp European broadsword could too...
and I agree, Middle Eastern and Indian swords are also often ignored. It seems that often it is the Chinese, Japanese, and European swords that people are concerned with... Where are the archipelago blades? The dha/darb? The shamshirs and khandas? The saif and the toukuba?
