I believe his blades were through hard FIRST and then he figured out how to
draw the spine back only by 1 point on the RC Scale. He said there was a hamon
in every single blade, but if a blade is differentially hardened or tempered, simply
grinding on the blade with an 80 grit belt would show a very faint line atleast
without any polishing of any type.
You can get an edge hardened line on A2 using a torch. (according to Hartsfield
this was NOT how he did it though)
The edge hardened line was polished out using Pumice (he said)...powder or stone...
who knows???????

Daniel! Try again!
How did Hartsfield get a hamon on A2?? That's the question!
