    Looking forward to your input.

    After reading several DS, 3V has better wear resistance and Tuff has better toughness.

    I personally prefer high toughness steel on survival tools. Therefore, some body suggested 5160 or S7 are good choices for supreme toughness.

    Yes, 5160 and S7 have great toughness, but they are not stainless. DBK youtube channel claims "a survival knife is a knife you dont need to care very much" or something like that (link A, begin from 16:00) and i agree. I love kinves and i would still clean them in the field, at least keeping them dry. Therefore, a stainless steel is not a must to me and i think 7.5% chromium is pretty enough for semi-stainless. (Zapp, 2019)

    Back to the topic i would pick Tuff over 3V because it offers toughness very close to S7 (Zapo, 2019) yet have the semi-stainless ability as 3V dose. Also, Tuff contain slightly less carbon (Zapp, 2019) than 3V and it makes Tuff less prone to rust too, theoretically. (i know their C content have only 0.15% difference, thats not significant in rust resistance and i know pointing it out is kinda stupid)

    Here is the counter argue, 3V has better wear resistance but still has a good amount of toughness.

    In a long run, every knives has to be resharpened. It is no exception s to 3V knives too. Also, haveing very basic sharpening equipments in the field, 3v could be very difficult to work with (link A, begin from 14:00). On the otherhand, Tuff has toughness very close to S7 yet have a wear resistance equal to A2 (Zapp, 2109), which i think it has enough wear resistance because A2's wear resistance is not bad actually.

    In conclusion, CPM 3V used to be my favourite and i still love 3V. But... Zapp Tuff seems better to me!

    In the real world 5160, SK5, A2 would be just fine
    They don’t just transform in a pile of rust overnight lol

    Get delta 3v from carothers and use the thing. Steel analysis and YouTube videos can only tell you so much.

    What no magical INFI? It's like A8mod, but with unicorn dust and shaman blessings and the spirit of the ninja mixed in too.

    True. I heard it on the interwebs and the Youtubes.

    With a pure chopping knife it does seem like more wear resistance would be more a hindrance than anything since sharpenability is a significant factor with so much edge to sharpen. At the same time there aren't many knives available in Z-Tuff, with a few more options in 3V.
