Watch: A screen guard that claims to protect your phone even when attacked with a hammer and saw

Here is a screen protector, Holy Grail, which its maker says is made of tempered bulletproof glass. This solid sceen guard is claimed to protect your phone's screen from scratch threats and substantial impact. In this video, the maker demonstrates the technology by using hammers, drills, razors, keys, knives, saws on the screen. Though the screen in the video is left undamaged, we are not sure of other parts that might have been damaged after such severe attacks. Reportedly, the new screen protector ranks 9 on the Mohs scale of hardness - only a diamond ranks higher. The Holy Grail screen protectors are currently available for Apple's iPhones, iPads, iPad Minis, and for some high-end LG and Samsung smartphones. The Holy Grail is simply dropped onto the surface of your mobile device and you are done. If it's not aligned properly, simply use a fingernail to remove and reapply. Sir Lancelot's Armor Holy Grail screen protectors are available for purchase online. The product comes with a lifetime warranty, and its pricing ranges from $30.99 to $54.99 depending on the phone or tablet model.
