  S-1 goes by a lot of names.  For instance:    Seminole Hard, Falcon 6&4, 
67-Chisel, Vibro, Excello, Buster, Atha Pneu, Keystone, Alloy Chisel, J.S. 
Punch, Top Notch, XL-Chisel , Commando, Par-Exc,  Alco-M, Alco-S & Cyclops 
S1, Par-EXC., and last but not least Maxtuff.

Or so says Varco Precision Products Co..  Who also happens to have a very 
interesting tool steel reference guide at 
http://www.varcoprecision.com/tools.htm  But, it doesn't list flutagon.

If I remember correctly from a discussion many years ago on this list or 
over on the artmetal list, one of the main charateristics of flutagon was 
it's shape.  That is, the sides were fluted.  I also seem to remember that 
it was an Atha product in the Atha Pneu family, which is S-1

The S designation means that it is a shock resistant tool steel, whick is 
why it is used in puches and chisels and other such tools.  The H 
designation means that it is a hot working tool steel designed specifically 
for working hot materials.

Bottom line is that if you want a good steel for a thin chisel for hot 
working, then go for the H-13.  I've got chisels made of this stuff and 
it's tuff as can be.
