Well, it’s the latest thang, in the world of edge treatments, for long lived ultra-sharp. The latest thang in a long line of latest thangs perhaps. 🙂
Yet the experimentations offered to us on the web by the various advocates seem convincing ……….. Who here, I wonder, has tried this method of sharpening; and what have they found?
A short summary is:
Make a primary bevel (shallow but can be otherwise); then a slightly increased-angle secondary bevel; then a rounded edge with 5 seconds of buffing on a cotton wheel charged with buffing compound at about 45 degrees. The 5 seconds produces a teeny-weeny round-over at the very tip of the edge, which acts like a normal sharp edge but is far more resistant to wear or break-down, even in lesser steels on hard timbers.
The experimentation and evidence via subsequent microscopic pics of the edge seem convincing. Theories are offered about why such as edge holds up so much better, even in poor steels …. but these are still theories.
Here’s two links to descriptions of the technique and the experimental results.
