  • 440B vs 440C BladeForums

    Mar 22, 2019 · I see AlphaKnifeSupply is now carrying 440B knife steel. Since there is almost no difference in cost between 440C vs 440B, is there any real reason to choose 440B over 440C? I realize Randall Knives use 440B, but I always figured it was due to cheaper cost. BUT 440B is almost twice as expensive than AEB L.

  • comparison AUS8 A versus 440C BladeForums

    Feb 27, 2014 · I have used both and really find little difference. Perhaps the 440C would be slightly more stain resistant, and the AUS 8A would be a bit tougher. I don't think there is any difference in edge retention, but if there is, I would give it to the AUS 8A. In practicality, it won't matter which you use, availability would be a bigger factor in choice.
