O1
52100
1095
depends on the person heat treating it. in 1095 rat does an insane heat treatment. the knife has great edge ret and will take a crazy beating. i don't have a rat yyet but i'm really thinking about it though from everything i'm reading about them.
Not to sound like a jerk, but if you don't have one then how do you know about the heat treat? I would doubt people using knives of the same steel from different manufacturers could tell a difference in steels much less having never used them.
Not knocking you but Rat has lots of fanboys and while I'm sure they are great knives made by great people, there is only so much a certain steel can do no matter how much hype they get.
Steels like O1, 52100, and 1095, for example, can probably only be really appreciated in larger blades, mostly fixed blades, because few people stress their folders enough to matter.
