No dents at all and I love it.
With wood i use to get a ding in the shaft every week. I kind of became a pro at removal. With my CF shaft I have not had one ding in the past year that I have used it. From what I've heard you really need some force to ding these things. It's not impossible but I can be done
They are pretty smooth. I kept my wood shafts smooth as glass and CF is about the same.
No need for a glove. I heard stories of the shafts turning peoples hand black or getting calluses. NOPE.
I would recommend carrying a towel to keep your hands clean and shaft.
