Imagine that you have a razor that originally had a blade that was half or quarter hollow ground. Now imagine that much of the spine has been honed away but there is still perhaps 4/8" of the blade remaining. Would the razor approach shaving like a wedge? If so and you like the way a wedge shaves, you might be able to restore one of your very worn razors into a wedge-like shaver. Or am I missing something?
