Thread: Difficult blade.

I will try to explain my theory on what is happening, and it kind of fits with what Oz said too. The fat edge has been beat up and rusty for a while. All of the fatigue goes past the edge. Kind of like when you file the serial number off of you handgun but the lab guys can use acid on the steel to remove the damaged steel and the serial number jumps right back out again. The edge is sort of like that. You can make it smooth but the underlying damage is still there. By killing the edge hard, it takes off a bunch of the damage steel. The edge then gets honed back up again. If it does not come back nice and even that is because of the damaged, weaker metal pushed back farther than the health steel and it need to have it happen again to get the steel even and healthy. That is sort of how it all wiggles around in my brain. Of course it is an unproven hypothesis but helps me to make sense of it.
