I just completed teaching a weeklong course at Campbell Folkschool that
dealt with period motifs.  The tools the students needed to make mostly
(90+ pieces) came from S-7 (1/2" dia. 5" long) which was hardened in brine.
They were used, without tempering, under treadle hammers in both hot and
cold chasing as well as hot cutting and slitting.  Almost every tool was
successful, overheating killed a couple, and no one had trouble with the
heat treating process.  The tools were forged, nomralized and hardened at a
somewhat bright orange and quenched in  brine (a mix of four gallons of
water to two containers of salt).  Too-hot resulted in brittle tools, so
feel your way through the first times.  The only problem with S-7 is that
it gets hard enough in air to make filing a curved chisel tough.  It is not
S-1     but it will do...............
