I can't figure out what kind of steel is used in the Rescue. The Triage is N680 steel.

If you need an O2 wrench or toolkit with your knife, pick the Rescue. Rick Hinderer is a no-fooling genius with knives, and while I don't own any Gerbers I would not hesitate to buy something with his name on it.

I do have some Benchmades (RitterGrip and RitterMiniGrip), and they're the best folders I have for one-handed blade deployment. You won't often catch me without one of them on me.

For myself, not needing an O2 wrench and being the curator of a collection of multitools (and so not wanting toolkits with folding knives), I would pick the Triage.
