Scratch test shows how Ion-X glass fares against keys, knives and other abrasive materials

Unbox Therapy released on Tuesday a scratch test video showcasing the Ion-X glass that'll grace the cover of the Apple Watch Sport. Unlike sapphire glass which was subjected to similar torture and passed with flying colors, the Ion-X glass material did succumb to the scratch pressure of materials such as sand paper. You can "watch" the torture test below and share your reactions in the comments.
