Thread: Best way to fix a frown?

The lifted spine as mainaman said is a great suggestion,
it is also one of the better techniques to have in your bag for chip repair and such.
I have only bread knifed one blade in the traditional sense,
at least for repair purposes, I do not consider a feather light drag on the corner of the stone bread knifing.
Doing the lifted spine allows you to quickly remove metal from the edge and maintain a rough form of the bevel,
when you go to reset the bevel you will have much less metal to remove and it goes exponentially quicker.
