I did fencing a few years ago.
It’s more difficult to harm someone with a fencing foil than with a fountain pen.
Back in a college fencing class I practiced with a beautiful healthy young lady who had no breast padding. I did not realize she was getting very sore and angry at me as I kept scoring hits on her chest area (wasn't trying for there in particular, was just easiest place to reach). I found out how sore and frustrated she was when the instructor called a break; she immediately stepped up to me and rammed the foil at point blank as hard as she could into my stomach area. The foil bent in a loop with the hilt only inches from my tummy. It hurt a bit, but did not do any real damage to me.
I made up with her eventually, and we have been married for 27 years...
