It was a pretty nasty dig. I'm not sure if you saw the wire edge that I fished out of the block and positioned next to the axe for the photo-op. That is my "hardest" axe. It was stoutest axe at 14 degrees. I used that axe in competitions in the US and Canada when the wood seemed a bit tough. It held up in some of the gum species in Australia. The damage occured when I was practicing a springboard pocket. You end up coming into the block heavy on the heel and fairly straight in. I was able to rough in a new edge with a file but a guy over there finished it out with a Makita 1" belt sander with a zircon belt. My other axes (pictures on the way) are lower in carbon and tend to bend before they break.
