I'm sort of like that until the first "character" mark. Usually, though, I do carry a "hard use" knife like my Ka-Bar/Dozier folding hunter and try to baby the new ones for a bit. Once they get by the "honeymoon" period, they don't get treated so nicely. For the most part - a little scraping, cardboard boxes is about as hard as it gets. I do like keeping my blades as nice as possible, but I don't mind it getting some "character" either
Interestingly, when I got my Buck/Strider 887SBT Police Advocate, it's first job was chiselling out a door jam for a deadbolt I was installing, and it's second job was digging in the garden and doing some "sod busting". It just sort of blinked at me as if it was expecting some "real work". The gardening portion dulled the edge pretty good (it doesn't like rocks) - no chips, and I got the edge back pretty easy once I ran under the tap to find it

I don't think I would have done this with any of my other folders - not that they couldn't have handled it, but just something about this one, demanded it.
Some of my fixed blades get terrorized the odd time, especially if it's a tool steel one that I've made, though I haven't made one this year (just too busy with work, etc) more for testing than anything else - usually when a wreck a grind line, or something, I'll finish it up and beat it up to destruction or close to destruction (now it's a beater) just to test my HT.
