Got a Great Eastern #73 in the 1095, I like the knife a lot. Outstanding steel, cuts better than I expected.
Saw on the tube (Frozen Forged), what does it mean?
 
Found this quote below, in this thread -->: http://www.bladeforums.com/forums/s...Questions-UN-X-LD-Hammer-Tested-Frozen-Forged

From the factory:

Hammer Tested: They test a sample of every batch coming out of heat treat by pulling across a bow while hitting with a hammer. This insures they are not brittle.

Frozen Forged: At heat treat once they come out of the furnace, they 1) get an oil quench, then 2) a preliminary temper, then 3) are cryogenically treated to improve temper, then 4) heat tempered again to finalize process.

Hopefully I didn't mess up what he said too bad.

my guess,it is fancy name for heat treat process
once they come out of the furnace, they
1) get an oil quench
2) a preliminary temper
3) cryogenically treatment to improve temper
4) heat tempered again to finalize process.
