Subject:
I don't agree with limitation of your premise

Bill Tindall, E.Tn.
Chipping and rolling come from shear and bending forces: prying, twisting, scraping, digging.

These dulling mechanisms certainly could result from the forces you enumerate but they also result from impact on an acute edge that is not sufficiently tough or hard enough to resist these forces. For any given steel just start lowering the bevel angle and at some point you are going to see dulling by either chipping or folding at the very tip no matter how perfect the striking force. Or alternatively, bash the chisel with ever increasing force and get the same result.

I will not deny that technique can influence the longevity of a chisel tip but the steel and its heat treatment also has a profound effect on what bevel angle the chisel performs satisfactorily. Now Weaver has shown that the edge profile may be as significant a variable as the steel properties.

We need to not loose sight of Weaver's discovery by getting distracted by technique. A 30 second addition to a chisel edge preparation turned a $10 chisel into one that performed as well as any I have on the bench, including a $70 LV. If this experience can be replicated by others it will be as significant as the rediscovery of the close set cap iron. Our role should be to encourage others to try it to see how broadly the benefit applies.

The goal is longer edge life. If someone gets it with sloppy technique and a more expensive steel it is the same result as getting longer edge life with better technique. Now we have a new variable to explore to reach this goal.
