Oh, I forgot: Wrapping in stainless steel foil is commonly done for
onesies and twosies of alloy steels, but I don't know if it's
effective enough for plain-carbon steel. Maybe.

It works for O-1. I smear some Ivory soap on the steel and add charcoal to
the pouch for good measure. The cutting tool comes out light grey after
quenching and cuts relatively hard steel like truck springs with only
minimal grinding or honing.

Tin can steel works pretty well if you don't have the stainless foil. I
leave one end open and cram in charcoal so the tool will shake out easily
into the quench pot.
