6 - 21: Astronaut Knife

On the 50th anniversary of the first steps on the moon, four bladesmiths compete to recreate a space-age M-1 NASA Survival Knife out of ball bearings. These knives must not only be worthy of interstellar flight but also overcome a triple strength and durability test. Only bladesmiths with NASA worthy engineered blades will continue onto the third round to return home and construct a Spiked Mace. Which smith will blast off past the competition, earning the title of Forged in Fire Champion, and a check for $10,000?
