The family jewelry store back ground has to answer the "your wooden table did that"?
Metal types does several things on a hit. Nothing at all, moves the metal but stays on the object (platinum), light surface scratches or shatters (titanium/tungsten), or flakes off the item when scratched and loses the weight (gold).
On a "hit," any hard object can surface damage metal. Diamonds can shatter too with simple hits.
Strong, yes. Indestructible? no. Surface damage? of course.
When I mentioned the lettering, I'm saying that look how deep they are next to your nicks. So no worries.
Shrouded barrel. Don't worry unless it's the barrel that marred.
