So if it is rolled over like this. That means it got really stinking hot right? They took it back about 5/8". Got any recommendations?
No.
Rolled edge like that only means,in a relative sense,that the tool was tempered so as to bend rather than break under impact of that specific force.
The key word here is Relative,as the hardness of any edge-tool can only be a balance,a compromise,between several aspects.
Two major ones are that greater hardness is always coupled with increased brittleness,and lesser hardness with this erectile dysfunction of edge.
So in this case rolled edge means that the edge of that Hardness+sharpened at that Angle+used in that Material has bent rather than chipped.
Equation changes with any change in any of it's variables.
For example if the angle of that grind was increased than maybe when the edge would've encountered say that knot it would have held up,retained it's shape.
The obverse of this is that then it would take more force on your part to penetrate into material,to start and maintain your cut.
And so on,with each of these several factors,in degrees.
However,it is indeed possible to run into a tool-edge that has lost it's temper due to overheating.
In this case it's hardness would roughly be equal to that of any untempered steel alloy.
A simple analog test would be to test-scratch it with a sharp corner of a new,un-beat-up file.
Try scratching the tool,than a piece of some known untempered steel(un-temperable would be most reliable,like a chunk of structural angle/plate/I-beam et c.).
Do it a few times back and forth with equal force and you'll get a fairly good idea.
(this is also not Absolute,as most alloys suitable for edge-retention would even in annealed,softest,state be slightly harder than dumb iron,but the feeling of lack of resistance will still be there,you'll just Know).
