The knife test goes well and the initial results from the hammer test are very positive indeed. In general use - if you're not expecting regular bouts of violence involving DIY tools - the phone's screen should remain in good condition.

Watch the hammer and knife test video from around three minutes in and you'll see quite a show; both alarming and funny in equal measure.

Just don't take it too literally. The battery really needed a going over before whizzing around like a Catherine wheel. It's extremely unlikely to happen in your pocket.
