45 degree X stroke should do the best at keeping the least amount of bad wear off there...

You have to watch the honing progression, the bad wear will suck you back in, sorta like ruts in a muddy road... I would recommend using 1 layer of electrical tape to get the edge correct on there, it is like grading the ruts out of the road...Using a marker to paint the edge also will give you a fast visual reference..
Swooping off the toe will work, to get the edge sharp, but that is not really the correct way to hone it.. Your real objective is to try and reduce that bad wear not just hone over it

I hope that made sense

Basically go back to the road analogy, you can keep driving down the ruts, or you can fill them in a have a nice even road again....
