I ran the edge over my thumbnail and they did not disappear. It's amazing how you think you have it and when you really start examining your edges you find how far you have to go.

This is probably the problem, if the spine is worn thin the angle will be off and the edge/bevel will be to thin to support the structure of the steel. You may be able to get past this by honing the blade for a while at a lower grit, be sure to use tape so you dont lose any more spine. This will help to correct the geometry if possible.
BTW running an edge across a thumbnail will only dull what edge you have.
Does the temper of the steel "change" as the original metal is honed/eroded? Would the thickening of the metal of an often honed blade cause the edge to chip or not hold a bevel?
I have noticed knives fail to hold an edge as the blade width narrows after years of service. Could the same be true of razors?

I think I will invest in a USB camera eventually. At least you guys can see some pics.
As a theory & in extreme circumstances I guess it would be possible with something like a wedge if you honed into much thicker steel away from the original edge but I reckon it'd be hard work. :) Can't see it with a hollow unless you turn a 6/8 into 2/8. Not a smith so happy to be corrected.
I've heard differing opinions on that pertaining to pocketknives. I've had some old Case knives that had well worn blades that would still take an edge. They weren't 'working' knives though. Just carried once in awhile and cut a peach or a tomato every now and again. I've heard that the temper would change, be softer as you move up towards the spine, but I don't know that for sure.
Had those nibbbles on a Leader (that was a great shaver)... I think it just got honed so much it got to worn in some spots and the metal didn't hold up... I bread knifed it and start over to put a thicker edge on it..
