Which S&W model are you referring to? They're cheap knives. By that I mean to say that they're inexpensive, so you sort of get what you pay for.
In my experience, their QC is all over the place. Some of their knives are well put together (as far as cheapies go) and some are outright rubbish, so it depends. I have one of their cheap plastic handled "assisted" OTF models which is made in Taiwan and I like it. Granted, it's not a knife I'd want to use everyday, but it's certainly fun to operate and it's an interesting conversation piece. Ironically, my cheap $30 S&W OTF came sharp out of the box and locks up solid with no blade wobble in any direction unlike some expensive OTF autos like the Infidel which costs 10 times more.
Like I said, it depends on the model. I will say that the vast majority of Smith & Wesson knives don't appeal to me, so if I were on the market for a new "dependable" EDC knife Smith & Wesson isn't really a brand I'd be interested in looking at. That said, if you find a certain Smith & Wesson model that you really like then go for it. The joy in being a knife enthusiast is to get knives you like, not what the masses lure you into getting.
