It's a knife edge when it comes in contact with whatever surface - there is no give, it digs in hard and snaps rather than giving a bit or sliding like the plastic/composite parts.

Waiting for some enterprising aftermarket parts company to make the same shock towers in carbon, but route a nice rounded leading edge. I bet breakage would almost be non-existent overnight.

Or, as I have done, bend a small piece of spare lexan over that leading edge. I've tumbled plenty on carpet, and have not had a single issue. Others driving the same chassis have broken them when run without any protection.
