The science of sharpness

I stumbled on this website looking for information about sharpening an ax with a steel I never heard of- but I'm no expert on knives and steel.

If you're interested in the science behind sharp metal edges (I think technically the apex) , it's interesting reading.

Here's a scanning electron microscope picture of a blade with the burr formed.
