are you saying it causes bone damage or soft tissue injuries, I think it will take significant overload using silly weights over a significant time to cause any notable bone damage.
that's the cue for you to magic up a study showing kettle bells cause bone damage, as exposed to stren5hihg them, which is the normal outcome for percussive exercises ? the idea is to resist the wrist whip at the end, not to bounce your wrist to the extent of its rom, that will strengthen the soft tissue and the bone, with iut wrechpking the wrist joint
