Not only does this sound like trouble, it also is denying you and your players of an experience they probably rarely enjoy: the pleasure of handling brand-spanking-new Paulsons. It's kind of like having a child--yeah, it's kind of a PITA during the infant/toddler stage, but it only for a few short years, and they will never be as cute as that for the rest of their lives. So enjoy every moment.
And so your intent is to wear the edges off a little. Where do you think most of that worn-off clay is going to go? Rubbed off onto the other chips, of course. You're probably going to end up with various-colored marks all over the faces of the chips from contact with other chips.
