بیشترSep 2, 2014. #11. I think if I put a S30V, S35VN, and a 44C blade of the same shape and grind, no one would be able to tell the difference in edge retention, ease of sharpening, and toughness in a real world comparison. I am a knife maker and when I made my personal knife, I chose 440C over every other steel.
