Can the expression "tools of the trade" be used to mean something similar to "it comes with the territory"? or "the seamy side of the job"? Meaning "unpleasant things one has sometimes to perform as a part of job". Besides the obvious meaning "these are the tools of the trade", I sometimes heard people use it to mean "well, these are the tools of the trade (whether I like them or not)." I always took it to mean that it was part of the job and whether the person liked it or not, he/she had to do it.
Thank you in advance!
