Yeah, A friend had one blow up and part of it tore open his forearm down to the bone and 8" long. I saw the pictures, the muscle was nearly cut in half. It's surprising that they were able to save his hand functions. He still can't lift much more than a cup of coffee, but the hand works mostly.

Having one shatter without a guard would be pretty dangerous.
