It's a funny thing, but from what I understand, if you made a sword out of AUS-8 and took it back in time to the middle ages or antiquity -- a period of time when steel was still made by blacksmiths in small batches by hand -- it would end up being so much better than what they were able to forge by hand that people would think you had a magic sword. It would shear through the best steel of the day like aluminum, you'd start a legend. With your AUS-8.
Perspective is a funny thing, both theirs then and ours today. Isn't it?
