Interesting entry on self-defense website:
Q: Which is more dangerous, a machete, a Bowie knife, a tomahawk, or a kukri?
A: They are all useful tools and dangerous weapons. But I would say that the kukri is most dangerous. Not because of the knife itself, but because of who is likely to be on the other end: A Gurkha, 5’4″ of loyalty, bravery, and a smile that is not at all humorous.
