So I was browsing SOG knives earlier and noticed that on several knives they use Aus 6 steel. I've also seen knives from other companies with Aus 4. I was under the impression that Aus 8A was the best Aus steel. I've also heard that the steel type doesn't matter so much as the heat treatment. I was just curious if someone could give me the rundown on the Aus steel. Is SOG's heat treatment able to make Aus 6 perform at a better level?
