Frazer, this was in reference to a post I made on another platform (IG) where we were talking about 8670 steel and its ability to be a tough working knife steel.
The kind of knife I'm trying to make is a common bushcraft knife with the ability to withstand batoning and retain utilitarian qualities. Lots of info out there, I realize that. I've found some carbon steels are more prone to chipping than others and am researching carbon steels that are less prone to edge failure. Of course quenching and tempering have a lot to do with it, that is understood. Just gathering information at this time. 1080,1084 are tough steels also. Differential tempering does help to keep a knife more resilient to breaking as you mentioned above. Just was curious about "drawing the edge back" as I have not stumbled across that phrase before. Thank you for your response.
