What I meant was a straight edge, but with the rest of the blade in whatever shape that pleases you then when you come to hone it, you clip on the straight spine that enables you to hone the edge with no problems.
I have several razors that have uneven spines that make honing a pain - not from creativity but age. Maybe if you used an artificial spine you could hone them much easier as the spine would be perfectly proportioned relative to the edge.
