Spyderco G10 Endura in VG-10, here. It's my EDC. I've used it to score Hardyboard (concrete impregnated exterior drywall), I've cut small diameter galvanized and copper wire, I've used the butt end as a hammer, and I've batonned the blade through a small log. No chips, no dings, no rolls, some scratches, some scuffs. The G10 scales have eaten the right pocket of more than several pairs of pants. Almost all of the paint is gone off of the pocket clip. When I go snorkeling, I coat the blade in olive oil and just rinse it off afterwards. This is in the Gulf of mexico, and I use IWB carry when I'm doing it. In short, this knife is the best carry knife I've ever owned. And the VG-10 stays sharp for a surprisingly long time.
Spyderco for life.
