Fixing a chipped toe

[notitfortat]

I picked up a C-Mon Blackie the other day for pretty cheap at an antique shop. I liked it in spite of the toe and I'm a sucker for a C-Mon. I've never taken on restoring a chipped toe before and need a little advice. I don't feel comfortable taking the Dremel to it especially with it being such a hollow grind. Here is what I have to work with, a Naniwa SS 220, DMT D8C, a Naniwa SS 1k, Chosera 1k and various grits of sandpaper. Which of those would you fellas recommend starting with? And any tips to minimize the risk of doing further damage would be greatly appreciated.
