So TFA addresses the expense/waste issue. If you're using a safety razor (or a leaf[1] if you prefer the multi blade style), and are buying blades from feather or similar. Technique will eliminate ingrown hairs/cuts etc, The exfoliation provided by using a razor (disposable, safety, or straight) is something some people find desirable (see also microblading) YMMV Time and effort is more interesting to me. For me the time spent shaving (and on other parts of self care) is part of the value of shaving in the first place. This isn't a process that I choose to speed up As for travelling, I use a soap puck rather than shaving foam or cream, so TSA doesn't care about that, blades are more of a crap shoot.
