Personally, I use The "Spec Plus" products from Ontario Cutlery. They're just as good, and are a LOT less expensive. I carry one of their Bowie knives on every flight, and one of their survival knives rides on my flight gear. THAT's how much I trust their stuff.
I also own one of their "Black Wind" katanas. I keep it next to the bed at home. It's a near-perfect modern update of a classic katana, but made useful for hard field work.
