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?
I think if the spine lost that much metal it would have to be about 1/8 thick maybe alittle wider to have a blade 4/8 wide, but seems possible.
In some cases there might be a loss of temper in the metal getting close to the spine depending on tempering method of maker.
Theoretically your idea is sound providing bevel is not too big.
What's wrong with a large bevel. A full wedge is all bevel.
hence why you won't find any true wedges unless you get a VERY old blade. Almost all wedges have the slightest hollow so you aren't removing the whole face of the razor when honing it.Quote:

Ideally, if you wanted to use such a blade, you probably would want to grind the width down some to accomodate the lesser width of the blade.
If your razor originally was 8/8 and now is down to 4/8 I would not bother unless you regrind the spine. If it was 5/8 and now is 4/8 it probably would not be too much of a problem.
Best of luck!
Whether it approaches a wedge, in the limit, depends on the radius of the grind and the type of grind I would have thought. Probably the best way to visualise it would be to consider a straight line tangent to say a parabolic curve at or near the origin, and then take the limit.
