OK...ok....

Someone posted a question - "best survival blade?"

My question's more basic - "best STEEL for a survival blade...?"

Better yet - what's the best steel in your opinion, for each of 2 survival blades...

1) for wilderness survival 6.5" to 10"

2) for "urban jungle" survival 4.5" - 6"

INFI ?
101 ?
A-2 ?
D-2 ?
S-7 ?
5160
VG-10 ?
CPM10V ?
Starrett 496-01 ?

lots of practicla application questions - but edge retention, toughness and durability, corrosion resistance...are all musts....

Suggestions?? Opinions???
