OK - just remember guys - Pick a steel, ANY steel - the harder you make that steel, the more likely it is to snap, the harder to sharpen, but the longer it holds an edge - make your trade as YOU see fit
Change steel - you can get tougher (less likely to snap), harder, etc - sometimes at the cost of things like rust resistance - why do you think D-2 is well loved - good tough blades, holds an edge - but it rusts if you ignore it
Now - do some research into various steels - then decide what features YOU want - and realize that steel A hardened to say Rc-58 might be a LOT tougher than steel B at RC-58, but a LOT more prone to rust or taking a permenant bend, etc
