GAI cases are just as easy to crack open as PSA slabs. Using the angled screwdriver technique and a hammer work all too well.
Suggestion for all who don't want little plastic shreads flying around:
Using an old rag or towel, fold it in half with one half under the slab and hold the other half in your hand with the screw driver. All the little pieces get caught.
Legal disclaimer: (Don't laugh, there are too many lawyers reading this board.) I am not resposible for anyone getting hurt following my suggestion. You act at your own risk.
