Several years ago there used to be a site called KnifeTests where a heavyset man dressed like a serial killer put a variety of cheap and very expensive knives through horrific levels of abuse. Using the tip to dig through a 2x4, hammering it through a steel pipe, putting in a vice and standing on it, bending the blade back and forth, slicing a variety of materials including concrete. The one thing that really stood out was INFI steel. That stuff may as well be magic. It's honestly hard to even get anything made with it these days but if I had to trust my survival to one metal INFI would be it.
