Considering the HTC One's elegant aluminum unibody design it seems hard to put it through such punishment, but one user did just that, bringing a hammer, knife and key to it. As expected of the scratch resistant screen, it didn't really get damaged by any of the three, and the tough aluminum unibody chassis also didn't dent all that readily. However, this time the torture test was more thorough and exposed the weaknesses of the back and chamfered sides of the aluminum unibody design.
