Yeah, pretty much what you'll have to do. B/c if you want to keep the square but want the blade flat the only way to do that is to level the existing steel past the point of the missing part to blend it together to make one edge. Basically the backside of the chip is your new pre-bevel placement. It sucks, but I don't know of any other way around it. You could PM Glen or Lynn with pics and ask their opinion; won't hurt my feelings bro, they may know of a way I don't yet.
