The vulnerable spots on an iPhone are edges.
* The edges of the metal around the camera plateau.
* The edges of the metal around the front glass.
The TechWoven case, like most cases out there, protects the camera plateau edges just fine.
If you're worried that something pointed may drop onto the plateau, well, that sort of damage would damage the camera lenses as well, and virtually every case leaves lenses exposed.
If you're worried about scratches on the flat part of the plateau, you'd probably need something sharp and as hard as steel to scrape it. Where are you putting your iPhone that it will be in contact with something like that?
