Looks fairly course to me as well.Honestly it looks a little course to me. The grain should look silky and smooth. I have to ask the normal questions when it comes to grain. Is this forged or stock removal, did you do any normalizing, what type of steel, and what process did you use to get that result...
About the best way I've found to tell if grain is like it should be is to break an old file and hold that broken file next to the broken test piece. If it looks like the broken file, then it's good. The file will look like a greyish color with almost actual grain visible to the naked eye. Seems like I can see grain in that, so a tad coarse?
Rather than profiling a full blade why not a test coupon for checking grain?
No, I have no way to test the Rockwell.Were you able to measure the Rockwell hardness?
It looks coarse to me as well.
