Mtech is more or less specialised in the cheap knives... If the C is not write, it's very possible the steel is simply a 440A. Function of the heat treatment, it could be not bad at all. The problem with the 440 serie, some company heat treat it very hard and don't pay attention of the heat treatment. It's create blade with a very big grit, very hard. And hard to sharpen correctly. Or sometime that is the contrary, very soft blade which don't hold the edge at all..
