I agree an upgrade is due, but can’t see how it’d work.
The blade in the mock-up picture above wouldn’t close because of the slidey bit for the pliers.
As it’s such a handy tool for mechanics and metal workers, it seems like the T-shank adapter would be a natural upgrade.
I think my ideal tool set would be the Phillips driver with bottle opener from the Free P4, T-shank for files and saws, serrated blade, couple of flat drivers, and a pry bar/package opener. Slightly bigger locking jaws with replaceable cutters, too.
