That's funny, because a lot of people on AZB own Diamond tables, and I've never heard ONE of them complain about hurting their hands getting the balls out of the ball box....not ONE!
I got a diamond about 18 months ago and this was my only single complaint about the table. There were a few times I scraped the tops of my knuckles hard enough they were bleeding. The pool rooms I play league in has lots of diamond tables, and i noticed almost everyone of them has the black plastic ring around the ball box missing. I assuming this is because of people keep hitting them with their hands and knocking the ring off over time.
I will say on my table I took a fine tooth file and knocked the edge off the black plastic ring around the ball box. That seemed to help a bit, but I still occasionally will get a scrape.
