Survival knife #1 : S5 LE
Likes : INFI! Good size to batton, tough enough because it is INFI, easy to resharpen in the field. Can be choked up nicely for fine work as well.
Survival knife #2 : Hmm tough prob my SoDF
Likes : It is just [censored] tough and feels like it can smash through anything.

I'd prob also pair those choices with an environment focused tool. For winter/fall in forested areas a Gransfors bruks axe. In swampy areas a Busse Kukri would be amazing!

Few die from pushing on, more die from giving up
