My friend managed to do exactly the same when preparing a rabbit with his convex ground Fallkniven s1 - i was very surprised at the time at the severity of the chips, but have since learnt that it is unfortunately par for the course....
Fallkies have a reputation for chipping before they are sharpened ... I have a bunch and, when new, they all dinged a little bit one way or another... no actual idea why, but I have guessed at the possibility of heat treating partly pre ground blanks allowing for a little brittleness .. or something Fallkies, are lovely things but eccentric, I've found.
I do find that new knives chip ... whether that is a function of their newness, preciousness, user failure or just sod's law, don't know that either
All part of the service
