That looks like a crude version of the smooth, rounded tyre lever that I
use. Gave up with screwdrivers on modern paint cans because the metal is
too thin - had to use a plastic stirrer on one because metal was deforming
the side of the can where it touched.

If the can is very thin I use a screwdriver at 0 degees rather than 90
degree angle to the edge of the can. Lever up a little bit around half
of the can and the lid doesn't get damaged. I don't know how to
explain this but when you do it it is really the only sensible way to
open a paint can.
