Test Summary
A high carbon steel blade from a Ron Hock Tools.The edge was typical of high carbon steel blades (as opposed to modern Stanley chrome alloys), retaining a smooth edge during use.
Hock O1
Ron Hock makes after-market replacement blades for Stanley style planes. Initially he produced only blades made from O1 steel.The Test
April 2, 2002.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. |
