I have several of those opaque red handled craftsman screwdrivers, as well as several older, translucent w/red and blue. The red ones were (best guess) probably purchased around the '90s.
They are not the same. The translucent have more hardened steel, are not nearly as subject to the tip deforming. Another notable thing about them is they (red handled from '90s) seem to be much higher in zinc because they get a whitish zinc bloom on them. I can only assume this was done to counter people returning/exchanging tools due to brown rust forming, but they are definitely not identical to my other, translucent handled CMAN screwdrivers which would (if it had ever happened) likely chip off the tip before it abrading away, as well as no zinc bloom even after ~50 years or so.
Today, I still use some of them if it's just the closest screwdriver within reach, even after having to use a file to true up the tips to a larger size, but they are craptacular in comparison to the tips on Wera, Wiha, and other higher tier brands. IMO, a good set of screwdrivers are a lifetime investment so I don't at all regret not buying more of the buck a piece, red handled craftsman.
I also, am mean to my screwdrivers, but not using them for unintended purposes like a pry bar (unless it's just to get the lid off a paint can, etc). If it was lighter duty use, they weren't a bad value at $1 but today they have to be seen in context of cheap chinese (and more so the Taiwanese) offerings where you can get equal quality for a buck a piece in a set, without even having to adjust for inflation.
Possibly you are correct that they were the same but for the color handle, if bought in the same era. If so then everything CMAN was already crap by the '90s.
