I wonder how they kept from killing eachother in those saber duels? I guess if you're skilled enough you can just slice the guy a little bit rather than disembowling him? I saw some Mensur "academic fencing" videos on youtube, and it looks like they stand so close to each other you wouldn't have room to really wind up and dismember the other guy.

On the other side of the whole "inhumane" coin, I read a very long article about curved vs straight cavalry swords with lots of journal excerpts from cavalry officers, and it seems the wounds caused by a curved saber are much more gruesome than those caused by a pointy sword even if they aren't any more deadly. For instance it seems that if you slice somebody's face across their eyelids, their eyeballs tend to pop out. Perhaps pointy sword dueling was preferred for avoiding that kind of gore.
