For general use, and knowledge of older safes made by companies no longer in existence, perhaps.
But, for anything that’s still sold today (or at least the company still exists), can’t you just look up the directions on the Internet direct from the manufacturer. Or, call them up and talk to someone about the user directions.
Even stuff where the company no longer exists, I bet you could find a large number of directions somewhere on the Internet with the correct steps. You can find a manual for just about anything from some niche repair or resale sight these days.
