I check my edges with my microscope after stoning each grit. I've never seen a burr. Ever. Am I doing something wrong, or are they just too small for my 185X 'scope?

Not sure. I think they are just too small to see at around 200x magnification. Have a peek at these electron microscope pictures of knife edges. Many of them show various amounts of burr.

Absotootley fabulous images. I'm always amazed by the amount of trash that seems to collect along sharp edges. In the navy, we would call 'em "dingleberries." Here, I call 'em "trash collected along sharp edges."

I know very little about these electron microscope images; I simply came across them in another forum. I thought they were stunning!

I can't confirm, but I heard they were a side project of some researcher, but unfortunately that researcher is currently too busy to continue the project. Hopefully, we see will see more.
