First is to remove any sticky labels that may cover a securing screw.

Good idea. However, I have yet to see such a screw on any laptop
power supply that I've torn apart. There usually isn't any room for
the required plastic pylon inside. There is also some safety rule
(double insulated???) that requires that the unit NOT create a shock
hazard by allowing the user to open the case. That's why they glue
the case shut, and not just snap or screw it together.

Refining point 1 , place in vice with the weakest point in the line ,
where
one of the cables exits.

I beg to differ. The ends are usually not very strong or well
secured. Compressing the plastic case at the ends is likely to break
the plastic, and still leave the long glue joints along the sides
intact. Best to break the long side joints first, and the ends will
just fall apart.

A guitar plectrum is best to start with as a pry-bar as minimum damage,
progress to screwdrivers etc later.

Yes, that should work. However, at $3/ea, I'm not thrilled.

I think the favored tool is a "spudger" from telco tools and the
favored tool for prying apart Apple products. Whatever works that
won't shred the insulation and shielding inside. Avoid anything with
sharp edges, such as a screwdriver.

Just this last Saturday a Boss PSC 2306 9V, 1A smps "wall wart" psu.
Under the label, a recessed 3mm a/f screw. After that squashed across
cable-weakened short side end in a vice , then other short end, then long
sides and plectrum.
