how i achieve a Hamon
KHalverson:
pappy
i'd ditch the used motor oil.
i used it many years ago when i got started.
canola works so much better.
warming the oil up speeds the quench.
most shallow hardening steel like whats in files and saw blade steel require a fast quench to harden properly.
thats why they get so hard in water or brine but for a larger piece of steel like a knife its too fast and cracks them.
the tiny amount of clay on the cutting edge is just a little insurance.
KHalverson:
here is the blade after 4 minutes in the vinegar.
it takes about a minute for the hot vinegar to start etching well so this is about a 3 minute etch.
next I rub out the blade with ultra fine steel wool and tooth paste.
the blade can also be polished further by rubbing out with pummice or buffing.
i know there are other ways to do this but this is how i do it.
i hope it helps some people.

That turned out nice. What happens if you leave it in the vinegar longer?

Deeper etch.
Pits in the steel.
