Generally you're looking at an ultrasonically welded case, or a glued/solvent
welded seam.
You cannot get it open with no damage.
Repeatedly running a sharp blade along the seam, or a Dremel with an abrasive
wheel or saw is probably as good as it gets.
A few can be opened without damage merely by levering.
In almost all cases, you're looking at repairing the seams afterwards.
