Thanks Bud for pointing Larrin in the right direction. Yes it is confusing Larrin and since your membership began well after the original edge rolling thread began we're happy to give you the Cliff's Notes recap here. This whole project is a spin off of a question that was asked a year ago "why are burrs so malleable?". The writer was simply asking why the steel that forms the burr appears to have much different attributes than the steel it emanates from and particularly with regard to ductility. As the discussion progressed the question was extended to finished edges as well. Then the discussion was extended further to ask whether or not HRC hardness levels above a certain level are contributing to any added resistance to edge rolling. Then blade/edge geometry and steel type entered the fray.
Preliminarily, early tests indicate that there are other or additional factors at work here with regard to very thin edges and that they do not seem to adhere necessarily to conventional wisdom. That's what we are testing for. Don't put anything you glean from these reports in the bank just yet though. There may be many variables at work here that we are not yet aware of and that includes our test processes. We and our test partners are just banking data at this time, we'll try to draw conclusions later.
