Don't think those tools were invented yet during the 1970's when i was in the AF.
And working around jet aircraft you had a certain amount of tools in your CTK, (consolidated tool kit) that were authorized to be in there, and nothing else.
A highly inventoried tool system, if something got lost out of the "kit" you were in big trouble until it was found, or they would ground your aircraft, or the ones on that side of the flight line, until it was found.
