ELI5 - Why all those Africans who had their hands chopped off at the wrist with machetes are alive, but people who slit their wrists with a razor blade aren't.

Well first of all many aren't, plenty of people who lose hands die and plenty of people who slit their wrists fail.  A lot of it comes down to treatment, if the arms can be sealed with pressure/cauterization etc. the victim will survive.  Cutting in that manor is much easier to fix than lengthwise cuts (which many attempting to kill themselves use due to it being much harder to stitch shut). Remember the wrist cutters want to die, whereas those that lose hands do not.
