Fuses, for as long as I am aware, have been designed to be visually inspected for failure ... if it is black ... it's life is very much likely exterminated.

Well, unlike you, in the first place I don't get into some kind of childish hissy fit over the issue.
In the EXTREMELY rare situation where a fuse looks visually good, but seems to me to possibly be the culprit, I simply pull another fuse on the block of the same rating and swap the fuses for re-insertion; I do this for the reset-able circuit breakers also.

Yep, that next question should never be asked.
