They typically use a specialized knife to cut this urethane adhesive on
windshields and other autobody panels. (The blade used to be heated
electrically, but these are falling out of fashion. The old style
adhesive was not urethane, but rather more like tar. You had to melt it
as much as cut it.)
These knives generally are small and have a hook shape. The have a
cable, with a pull handle, attached at the root of the blade. You use
one hand to guide and steer the blade through the adhesive, and the
other hand to apply major force to the blade. Quite effective.

Be sure to buy extra blades as they are damaged and/or wear out routinely.
They also use a thin sharp blade on a vibratory tool, or a small thin
hook blade with a special cable handle for the tool itself, to cut the
adhesive. Pretty much a "power" version of the manual tool above.
A visit to your local windshield replacement shop might be a useful to
see how the professionals make short work of cutting these automotive
urethane seals.

You need a really thin blade, you just want to cut the adhesive, not the
metal. I used one of these:

With a blade like this: https://amzn.to/373V75P
The tool oscillates really fast and slices through the adhesive like
butter. You just run it down the side.

I used pry-bars and screwdrivers & putty knifes on a 2013 leaf battery
that was glued together. Now that I know what is inside (and how to not
hit it), I'd use an air chisel.

FYI: I have opened the 60kWh LEAF packs, it can be done with a vibrating
multitool blade. Much easier than a Tesla pack!
