I would think it only costs a couple pennies to extrude some white plastic into a mold then add some brown paint to it.
As far as HT goes, this one takes a really sharp edge quickly on the bottom of a coffee cup. This tells me it's a usable blade steel, but it's definitely a mystery as there's not anything marked on the knife or package at all.
It's some kind of steel that easily sharpens and can make at least 50 cuts on some thick cardboard
And still cut paper.
I got one that I can actually call a knife, but who knows how consistent they are.
