Unless one can identify something in the wood structure that has a greater tensile strength than the steel cutting it then adhesive wear can be dismissed as a relevant mechanism.

The mineral content could provide abrasive wear. The volatiles and extractives could promote corrosive wear.

As Kato and Kawai demonstrated factors that increase shaving pressure promote wear in the high pressure areas. One does not have to conjure different wear mechanisms to explain the different amounts of wear observed at different rake angles relative to the grain orientation. These results can be rationalized by the difference in shaving pressure on the blade tip.
