Another way of telling if a blade has an edge: stand with some light source behind you (optimally a window) and look at the edge. If don't see the line between the two side of the edge, and you feel you are squinting then it should have a sharp edge.
>heated the handle to burn its way into the wood
Would not have thought about that. Most likely won't try it.
>ruin your hardening
Yeah, slow cooling from high temp soften the steel.
>chainsaw file
I don't have a chainsaw file. Maybe something similar.
