Being one of those ignorant people who actually "use" their pocketknife as a daily tool--no doubt, one of Jackknife's "unwashed masses"--perhaps I can be permitted to respond?
One of the things I find amusing is that I'm not particularly hard on my knives compared to many of the older folks I grew up around. It is only "hard use" relative to the folks who treat their knives like holy relics: something to be protected and coddled, like those who buy knives with "pocket-worn" covers and apply a faux-patina to the steel, then carry the knife in a little purse to protect it from the contents of their pocket and the world outside. You know who I mean: the folks who gush like little girls over the latest star on the cover of the teen magazines when a company brings out a "new" model with covers made of "apple-rootbeer cat-scratched baby-panda bone," or bash the folks who buy imported knives that actually meet their working needs rather than the latest domestic-boutique-manufactured homage-to-the-working-knife that doesn't meet those needs. (Some amongst the hoi polloi might almost be tempted to ask if "poseur" would be a better way to describe these folks than "collector"--but no, we mustn't question the motives of our betters.)
In the past week, I've "abused" my Schrade-made KeenKutter jack while repairing storm damage to the home of a friend's widow. The knife has peeled wire, tightened screws, cut the steel bands on bundles of 2x4s, opened boxes of nails and bundles of shingles, beveled the edges of studs and siding so they could be fit into the surviving construction, cut tarpaper and shingles, spread putty on windows and tar in roof joints, cut window screening and pressed home the splines that hold it in place, split kindling for the little fire I used to make coffee, and sliced up apples for snacks. It has been in-and-out of my pocket a hundred times a day, been sharpened on the medium India stone in the toolbox, and cleaned and oiled in the evenings so it can go to work the next day.
Such is the life of a working knife.
