a nice collection of (electron) microscope photos of blades
best explanations I've found about how much sharp are knives

I've done a fair bit of this myself, though only with an optical scope. I know the owner of that site a little through correspondence via email and a few message boards. Todd is a nice guy.

Here is an image through my Vanox of a straight razor edge at 400x. It's only through the eyepiece with a phone camera, don't have my permanent camera setup finished yet.

Excellent effort, thanks for the link.
No excuses for not getting a reasonable edge on the mower blades after reading all that.
