Are we talking about the same tools?
We handle a fair few Narex chisels and I've yet to see a single speck of rust on any of them, the blades should be covered in a very thin lacquer and then lightly oiled. The photo above was taken a few minutes ago and is just the next chisel out of the box, it hasn't been selected as a particularly perfect example.
The grinding marks should be consistent, fine enough that they can barely be detected with a fingernail and the surfaces true enough that the backs can be polished out with minimal effort.
The self-tightening, splitproof cup ferrules are made out of steel, an appropriate material, and plated to protect the surface. Yes, they are bigger than we are used to on a western European chisel and look a bit different, but in purely functional terms they work extremely well - much more reliable than brass ones in fact.
As Peter said, the lettering on the blades is printed and will come off if you remove the lacquer (warm sodium hydroxide solution). They print them because chrome manganese steel is resistant to etching, like the paler layers in pattern welded damascus steel. Engraving would push the price up and slow production to a crawl, hot stamping would require delicate lettering in the forging die reducing their working life. Other suggestions welcome...
The ethos of Czech manufacturing is all about producing things that work well, last a long time and lots of people can afford.
In a world full of far eastern 'first minimise the unit cost, then decide what the product will be', and far western 'flawlessly finished, hugely expensive, oober desirable, sorry, what's the product again?', a straightforward, well made, functional item stands out like absolute silence.
