Re: studying edge failure...somewhat obscure

Steve Voigt
I'll echo Wiley in asking: is it the geometry, or is it the medium? If it's the geometry, it should be replicable on a stone.

the very low angle cap irons that ward and matheison made always work better in a brisk cut than a more modern emmerich type that's highly sprung and more blunt.

I don't understand what you mean here. Spring (which I define--and measure when I'm making cap irons--as the gap between the cap iron and blade before the screw closes the gap up) and angle (not sure what angle you're referring to; do you mean the overall shape of the business end?) are two separate issues.

That last paragraph of mine is painful to read. Reminds me of Adorno, and not in a good way. Sorry folks.
