The edge was typical of high carbon steel blades (as opposed to modern Stanley chrome alloys), retaining a smooth edge during use.
As with all my other tests, I honed three front and back bevels using 15, 5, and 0.5 micron 3M micro abrasive paper.
The front bevel, 200 X magnification, after the 0.5 micron paper.
There may be a couple of 15 micron scratches that were not completely removed by 5 micron and 0.5 micron steps. A few 15 micron scratches would not affect the overall wear bevel size, but might contribute to failures at the edge itself. There are no such failures with this blade.
The front bevel, 200 X magnification, after 100 passes along 4 foot douglas-fir board.
The wear bevel is about 6 pixels wide, the edge still quite regular.
The front bevel, 200 X magnification, after 150 passes.
The wear bevel is about 9 pixels wide, but the edge is still regular.
It is typical of these high carbon steel blades that they wear a little more than more modern steels (HSS for example), but retain a smooth edge throughout.
