Looking at te grain today in better light, it does look a bit large.
But it also looks inconsistent. I don't know if the break can fool the eye?
The grain at the cross section af the bevel looks very smooth and uniform but other areas the grain looks larger.
Ferric etch.
The steel turned dark very fast.
I don't have any canned air or a compressor. So the air quench must wait.
I will make a small knife blank and test with a longer and hotter temper.
