The theory is sound, however, it fails to take into account a very important fact.
The flex of the hollow grinds will be more severe in the thinnest sections (i.e the center) as opposed to the ends where there is more support from surrounding thicker steel.
Its on a micro level, but it will cause more wear, and eventually, I imagine, a bellying of the blade. Of course this may take years to accomplish,
I like to keep them the way the old timer who made it intended it.![]()
