Yeah, I wouldn't worry about it. It's not unusual to find grit and rock in the bark and wood near the base of a tree. And certainly in the soil around it. This was our goal with optimized 3V, to achieve a level of durability at narrow edge angles against this kind of edge damage similar to other high performance steels like Infi. This is why we run our choppers harder than most, the dents are less severe when you inevitably do hit a rock. The steel is durable, but (like anything) it's going to take some dings if you're using it with abandon. Which is the best way to use it. Put a micro bevel on it at 25 DPS and get 90% of the dings out and go smash the shit out of some more stuff, that what it's for. If you pick up a real ding that's going to require water cooled powered sharpening, send it back in for some love.
