Summary

Description
English: Edge of a Leatherman Crater pocket knife after sharpening and stropping. Although this edge is sharp enough to bite a thumbnail, cut paper smoothly, or shave arm hair, the hobby digital microscope plainly shows an approximately 0.01 mm wide edge, which reflects light back into the lens. A truly sharp edge is too thin to reflect significant light.
