Thread: Science of Sharp

When I find it (unfortunately rarely !!) I am fascinated by the use of the electronic scanning microscope (SEM) for the study of blades.
Unfortunately, it is often used only in the analysis of the DE blades.

For science lovers, in sharpening there is a reference:

From the same blog user (now private, but just log in to WP with Google and ask for access via https://scienceofsharp.wordpress.com...request_access) ... a very high resolution image album Yellow Belgian after 300/800 passes and razor (bad) sharp on this.
But also side sections of Gillette Fusion and Feather (magnification 10k / 50k).

Along the way I found other interesting topics (in theory) ... mutilated by the bad choice of hosting for images !!!
