So I'm going for a hamon (first time wish me luck) and would like to keep that top part until after the final bevels are in to make grinding easier, I'm not a huge fan of grinding those pointy edges and don't do it much.

Is it reasonable to leave the top part as is and do the top curvature last? (Rough bevel -> HT -> Final bevel -> upper curvature)

Ignoring heat management, I know it's going to be a pain to grin that at low heat but I believe I can make do

Mousetrap for reference
