IBTL!
Seriously though, That's the way carbon vs stainless
used to be perceived. We've come along way since then.
It used to be that stainless was considered difficult to sharpen, but now diamond hones are much more readily available and more affordable. Carbon steels were believed to take a much keener edge, but edge retention was not as good as stainless, which was okay considering the ease of sharpening and pretty much any old stone would do.
Now we have much better stainless options, but carbon steels are still favoured by many for choppers and general outdoors type of usage.
