Titanium works for Mission Knives, but they are priced like the Busse Combat shop!
You just have to know where to find them. I've got a couple and although I haven't used them much, they seem built to perform well and I didn't pay near what they are priced. I have a fixed blade model that I usually carry canoeing because it won't rust no matter how wet it gets. And it's very light weight too.
