I have been opening up some slabs for my Dansco album and some were easier to get open than others. Some, if I got part of the seam apart, I could get the slab apart mostly intact. I still had to get a starting point though, and my method (a pair of side cuts on the corner) did damage. Some other slabs came apart in pieces. Unless someone has a special trick or method to getting them apart clean enough to go back together, i think it would be tough to do. I obviously do not know these particular tricks and yes, there was some blood involved.
