My friend has one. Not exactly sure what model, though. The handles are made of some kind of plasticky rubber - whatever it is made out of doesn't hold its shape very well, and is more akin to rubber than plastic. The "single" liner it has a piece of super-thin plastic that looks no thicker than tin foil doubled over a couple of times, and it's only on one side. It's made of mystery steel. Overall, it is the epitome of a POS knife.
On the other hand, it probably cost her less than $5. I may use my knives for a lot of things, some of them perhaps questionable like constantly cutting every piece of paper in sight, but on average my knives cost 20-30 times as much.
The question to ask is, am I getting 20-30 times as much performance out of my knives in comparison to a Frost Cutlery knife? She actually wants to buy a better knife, once I showed her the difference between a quality knife and a POS knife, but doesn't want to spend more than $40. Spyderco Tenacious or Persistance then. At that price range, I can say that those knives are definitely worth 8 times as much as the Frost Cutlery. Much above that, and I think we must admit we are facing the law of diminishing returns.
An example of how crappy a Frost Cutlery knife is, here's a video from cutlerylover from youtube. It's a 10 minute long video, but if you fast forward to about 8:45 you will watch the knife break on screen. He then proceeds to snap the knife in two with his bare hands, with what appears to be little effort.
