Rick McQuillanI always worried about cracking them out, but it turns out to be very simple and safe. Use a heavy wire cutter and nip off about an inch of one of the top corners. Then use a regular old table knife to break the seal. I have liberated about 30 slabs in the last few weeks with no problems. It works for PSA, SGC, GAI, and BVG.
