For it to have chipped like that, I would think there would have to be a problem with the steel, whether it be 1. the heat treat, or 2. the steel quality. 65Mn is a 1060 class steel, so should be exceedingly tough. But it will have more impurities on a regular basis than fine tool steels like A2, O1, etc.
Tell us about how you were chopping.
Cut pieces of pine on a block or on the ground (immobile)?
Or branches still attached to the tree that could move with the impacts?
We see many blow outs like that when chopping at unsupported branches.
At the initial blow the blade sinks into the wood.
As the chopping stroke continues the branch moves and all the force of the blow isn't going straight anymore.
The branch then twists the knife, and a chunk out of the blade.
I had the same problem with the 14, a very chip flew out and
Come a hair of getting my face! Weather was warm. The wood was springy and tough. The chip was an three inches tall by five long.
I sent them the blades, I haven't heard back from them. I've been running busy and forgot about them till a week or two ago and sent em in like they told me.
Bored, that sucks. I dislike sharp pieces of metal breaking off and flying close to people.
