For something in the six inch range I'd go with the Fallkniven A-1.
Good steel, and very tough. The only downside is the plain rubber handle.

You also might want to look at the Spyderco Hossom line of fixed blades.
the only real advantage over the Fallkniven is the (very comfortable) micarta handle.
This is the six inch woodlander.

Both of these knives are made of good stainless steel and are designed for bushcraft.
