I love destruction tests, obviously if anyone honestly intends to use a knife in the manner they do in a destruction test then they probably shouldn't be allowed to use a knife, but if for some insane reason I needed to chop up a metal drum it's nice to know how much the knife can take. My personal opinion is that any destruction test should be specifically designed for what the knife is meant to do taken to the extreme, an example is a destruction test where someone is using a machete as a pry bar is just stupid, but one where they are using a machete to try to chop or hack through progressively harder or thicker material until the blade can't keep going would be useful.
