Uh... isn't that the point of fakes?
No one really ever knows what's used on them. It could be 440C, it could be 440A, it could be Pakistani Pot Steel A.
It could be that funky cheap G10, it could be some thermoformed plastic, it could be recycled tyres.
Same thing with replica watches.
How many say "Real Swiss ETA 2824" or "Authentic Swiss Unitas 6497" and when your watchmaker pops the display back, he says, "... wtf IS this crap? That en't gonna take any parts that I seen."
Genuine products have something that fakes don't: authenticity and accountability.
Real companies get in trouble if they give you something that they don't advertise. Fake companies, on the other hand, don't.
That having been said, I wouldn't be surprised if it's plastic on the scales, and 420J2 for both the liners and the blade. Those seem to be the cheapest materials used in similar mass-production Asian knockoff factories working for genuine Asian knife companies (e.g. those that outsource for S&W/Taylor or the ones that make the funny copies you find in gas stations), and I dare say it's a hop and a skip to running them to make fakes "at night".
I don't really have a problem with fakes for fun. But you pays your money and you takes your chances.
That's how it goes.
