It IS possible and it's really REALLY tough. The plastic tool included in this set is enough to keep seams open where they show in steps 2 and 3 just wide enough for you to put something else in there. But to start them, I used an exacto like blade. When I did this job, I had 3 regular spudgers, the 2 tools provided here, 4 different style green spudgers from somewhere else, 5 large 'guitar picks' sold here to cut the glue holding new iMac screens to the case, the metal spudger, and an exacto type blade.
It was still an incredibly laborious job and although the iPod is back together and works perfectly, one of the seams is bent out a little.
