Strider uses G10 for their knife scales. It's probably as close to indestructible as you can get for materials of that type.
Mick Strider once shot one of his knives with a .45 to see how the G10 would hold up, and it did surprisingly well - dented but not destroyed. There were pictures posted of it, but that was quite some time ago and I can't find them now.
The carbon fiber grips are unique, look good and may even become collectable someday, but I have no problem with the move to G10, as it's probably a better material for the application.
