S&W Knives, in my experience, vary wildly in quality.
Some of the older pieces, traditionals for instance, seem to be decent knives.
Some of the tactical folders, however, are very poor quality.
My son gave me two S&W folders that he bought at O'Reilly's Auto Parts, one is a small "Cuttin Horse" lockback that I still have -
The other was a mid-sized liner-lock that I used for cutting cardboard and garage chores; the knife lived in the console of my truck for a couple of years. The wear on the knife in the picture is much worse than the actual useage would infer, that is to say it did not hold up as well as other knives, the coating started wearing off right away and it did not hold an edge very well compared to more expensive knives.
I guess that is a given.
The real problem with this knife was that the handles did not have any reinforcement at the bolsters, and they eventually cracked at the pivot pin, causing a catastrophic failure of the knife.
The knife had teflon washers, which held up well and were smooth. The black plastic for the handle was rubbery and allowed a good grip, but it smelled of rubber and transferred that rubber smell to your hands when you used the knife.
These are very cheap knives, and truly you get what you pay for; you can use them but be careful and don't trust them to stay locked and you should be fine.
I disposed of the broken pieces of the CKTACB and still have the Cuttin' Horse.
