This is an idea I have been thinking about... and there are a number of blade sharpeners out there for disposable razors, but none that I could find that gave you the ability to check if the blade actually sharpened. All the current solutions are classic whet stone designs. The problem with this approach is that you have to angle the blade just right to get a shape edge, and the plastic casing makes this very difficult. A better approach would be closer to the kitchen knife sharpener where you slot the knife into a V shaped sharpener. It would have to be very small, but I believe that it would do a superior job.
I was watching a recent nycnc video, and he said that he used a jewel's loupe to check the cutting edge on his end mills. Take this idea and add to it a sharpening tool and you have one device that performs a service and allows the user to inspect the sharpness of the blade. $24.95
