The blades were sharpened on a belt sander with the platen removed starting with a 15 micron belt, then followed with 9 micron belt, then power stropped on leather loaded with Chromium oxide powder from Lee Valley and finally finishing by hand stropping on an old leather belt.
David noted one felt softer and formed a burr during the power stropping. Both blades were very sharp, though one was significantly ahead. The best one is reported on the main page, the numbers for the second one were 70.0 (3.6) and 93.6 (5.2) on the thread and cotton respectively. It performed nearly identical in the hair and paper cutting.
Both blades could whittle hair easily, slice newsprint trivially, push cut newprint well, slice the paper towel with some difficultly, but not slice toilet paper readily.
