Fitz basically covered it.

What will say is that I've owned a bunch of knives over the years. Most of the live in my drawer, largely forgotten. The knives I put on my belt when I'm going off the pavement are one of my Ka-bars. 1095 might be a "standard" steel, but so long as you don't have saltwater around, it is hard to beat. I've never had that much of a problem with rust (read that as no problem), but even when I get wet, it is freshwater, with the exception of acid rain. .

D2 CAN beat it, for many times the cost. If you can spend the extra, do it. It is a great steel. But if you want a couple of identical blades, say one in the BOB, one in the car, one the earthquake/hurricane bag, then grab a couple of 1095s for one knife of the same design in D2.
