That's the results of the house O1 in cherry vs. the hock in the same piece of wood, alternating every 200 feet.

House O1 appears to have more wear, but slightly more uniform.

I think the difference between the two is insignificant and could be attributable to the LN plane being better fitted than the old Record.

This should give a purchaseable point of reference for the O1 results in the test (interchangeable with a hock iron).
