I beat the living piss out of my a100 which is considered by many to be the "gentleman's model". I'm talking; used it as a chisel at least four times once with a 4lb hand sledge for a mallet, many days of work on the river which plugs up and wears down most locks after a week or two, a bunch of thick nylon rope cutting (way tougher than manila rope), some cutting and prying of pine 2x4s, and some wire stripping.
I agree that many users on this forum don't really need the hard use knife they take pics of, but to each their own. Here's a pic of my A100 about a year ago, its significantly more beat now, but the lock engages very solidly at 80% (which is fine by me as its a solid lockup even under reverse pressure against the spine) Its the only knife I trust my fingers to with stabbing things, aside from my para2.
FYI I got this guy in 09 and its been my most carried knife since, and I use my knives quite hard almost everyday. And by that I don't mean by opening a cardboard box a day!
