This weekend I observed an epee fencer using a blue non FIE PBT mask (not that I think the PBT brand matters) fencing a DE bout take an unusually hard hit directly to the mask leaving a large mark and dent. The problem was that the fencer received small paint chips from the mask on her face and in her eye from the blow. After the bout we were able to remove the speck from her eye and no damage was done except to the mask the possibility of contributing to her losing the DE and a new rank.
My question is: Was this an unusual occurrence or does anyone know if this happens frequently? Is this less likely to occur with black mask?
