APPENDIX A:
THE CUTTING ACTION OF PLANE BLADES

by John Whelan

From The Wooden Plane: Its History, Form, and Function
By John Whelan,

Another major improvement in performance was introduced early in the 18th century, with the discovery of the benefit of the cap or breaker iron. A shaving riding up the surface of a single iron gains some leverage helping it to initiate a split in front of the cutting edge. The cap iron serves to break or to fold the shaving before it has gained too much leverage (E). With this help, a sharp, well tuned and finely set plane can cope with difficult grain.
