Not always Marco, but certainly from around 1975. I can certainly
remember popping E-3 (anyone remember that emulsion?) cartridges open by
hand, and I still have a couple of hundred E-3 cartridges I use for
reloading bulk film in.
Around the time E-4 was introduced Kodak went over to having crimped
cartridges ostensibly to avoid the cartridge opening when it was
dropped. You can get a grip to lever these off - it is basically a
steel "C" shape which is riveted to a circular piece of plastic with a
recess in it. The cartridge slots into the recess in the plastic and
slides back so that the steel "C" fits over the end piece of the
cartridge. A simple twist and it opens by hand - but it certainly can't
be refitted.
As you say, pretty much most manufacturers have gone over to these
crimped non-reuseable cartridges now.
