I still got a pair of decades ahead of me before I reach 60, but learned to really appreciate stainless steel as a young dock builder in my 20's... working on a barge, constantly cutting wet rope, long days in a salt water environment, and just one complacent day and even lower resistance and lower quality stainlesses would all but begin spotting up before the end of the work day. Carbons would just make those long days longer w/ the extra care and attention they demanded.
I also earned the appreciation of both realistic expectations, good sheaths and pocket clips, (using them), and even appreciating the cheaper stainlesses as well, as things "falling into the drink" was a real daily threat.
I remember when I set down my griptillian, 1st real "expensive" knife I bought myself that year for Christmas solely to use the upcoming spring on the rivers, and I loved that knife. Served me well into the summer months. Then while working one day; head motor running, barge deck vibrating, in the middle of manhandling and trying to set a 40' piling (so letting go was not an option), the colored handle caught my attention out the corner of my eye, vibrating across the deck, and I slow-mo watched it vibrate right off the edge of the barge and into 20' of the fastest current ocean inlet in NJ, as the tide was rushing out...
I also remember how mad my boss was one day when I dropped a sawzall, but I digress...
(Between rust and drops, the avg. lifespan of a tape measure was no more then about 2 weeks, so we would buy the cheap ones by the boxful)
In any case, for toughness and ease of sharpening, I'll agree that you can't really beat a good ol' carbon blade. But for good edge holding and rust resistance, (which can actually be all but a necessity in some cases), you can't beat a good stainless, and some of the stainlesses out there are still respectably tough, and some of the lower end stuff is still relatively easy to sharpen, so I think all steels across the entire spectrum, even the old school ones like 420 and 440 series, to any of the 10 series carbons, all the way to powder and nitrogen steels, etc. All of them have their proper place in daily knife use for modern day life. Depending on needs, wants, functionality, and cost, nearly everyone still shines in one category or another.
