Since I have a copy of an earlier edition of "The Mastermyr Find". I can 
say that the metallurgical analysis, shows most of the tools are pure iron, 
i.i.e.., less than .002% carbon. In the pieces they examined, no sign of 
case hardening, Some few pieces of cutting tools show a welded bit of 
steel, .4% carbon, as the cutting edge, but most of the iron  is as pure as 
can be, according to Appendix II, "A Metallurgical Examination of some iron 
objects from Mastermyr" by Sten Modin
