Hi guys,
I think you should check out this video:

or the manufacturers website:
Wicked Edge Precision Knife Sharpener
It seems to me that somebody had a very similar idea and went ahead and put it on the market. They claim that the device may well be used for straight razors too, that I would like to see. Looking at the different grades of sharpening stones, it just might be possible.
If anybody can find out more, or actually has hand on experience, I would be very interested.
