[TheForge] Oxygen cutting -- was suggestion for abana and local blacksmith groups.

[David E. Smucker]

You are so right.

We have become so used to using Oxygen for burning / cutting that it is easy
to forget that we have only had this for about 100 years.  Before that it
was saws, cold chisels and hot cuts.  "Tonnage Oxygen" was a product of WWII
and the development of German rockets.  It became the driving force behind
basic oxygen steel making.  About 60 % of the worlds steel comes from BOF's
today.
