A few filters possibly slightly improve my bad photos on webcam

I wonder if there can be any change in the quality
of steel over time for the better?

The fact is that for about 2 years I have not touched the sharpening
of this knife. Yesterday I had to sharpen it, I did it,
now it's sharp as a razor. In the process of sharpening,
I noticed that, compared with the previous time,
steel has become more viscous and hard.
